refactor: rename firmware from Plus to Solo

- FIRMWARE_VERSION: v1.15-plus.1 → v1.15-solo.1
- FIRMWARE_PLUS_BUILD → FIRMWARE_SOLO_BUILD in all platformio.ini and UITask.cpp
- docs/plus_features/ → docs/solo_features/ (all sub-docs moved)
- README: update all doc links plus new Documentation section
- GitHub Actions: extract GIT_TAG_VERSION in each build job (was missing,
  causing empty FIRMWARE_VERSION in builds); rename output files to
  solo-VERSION-oled.uf2 / solo-VERSION-eink.uf2; release title → "Solo VERSION"

 ## Firmware Variants
 
 Two firmware builds are published with each release:
 
-| Variant | Display | File |
+| Variant   | Display                   | File                                    |

+| **E-ink** | GxEPD2 250 × 122          | `WioTrackerL1Eink_companion_dual_*.uf2` |
 
 Both variants are built from a single codebase and share the same feature set. The `dual` in the filename means a single binary supports both BLE and USB serial — there are no separate BLE/USB builds.
 
->[!IMPORTANT]
+> [!IMPORTANT]
 > BLE connection has priority over USB serial. When a BLE connection is active, the USB protocol is suspended. When connecting to the companion app via USB, ensure to disconnect from BLE first or disable BLE directly from the device to avoid confusion.
 
 ### Flashing
+
 1. Download the appropriate `.uf2` file for your display variant from the [releases page](https://github.com/MarekZegare4/MeshCore/releases)
 2. Press reset twice quickly to enter bootloader mode (solid amber LED) - the device should appear as a mass storage drive on your computer
 3. Copy the `.uf2` file to the drive to flash the firmware
 
 Updating to newer firmware versions usually does not require erasing flash unless the release notes explicitly state otherwise. To retain your settings and data, avoid performing a factory reset after flashing unless you need to start fresh or encounter problems.
 
->[!WARNING]
+> [!WARNING]
->When migrating from official/custom firmware, backup your data and **perform factory reset** to prevent conflicts with existing settings and data:

-
-#### Downloading GPX to your computer
-
-1. Connect the device to your computer with a USB cable.
-2. Open a serial terminal at **115200 baud** on the device's serial port:
-   - **macOS / Linux** — `screen /dev/tty.usbmodem* 115200` or `cat /dev/tty.usbmodem*` (replace with your port, e.g. `/dev/ttyACM0` on Linux); to save directly to a file use `cat /dev/tty.usbmodem* > track.gpx` and stop with Ctrl-C after the dump completes
-   - **Windows** — open PuTTY (Connection type: Serial, Speed: 115200), or use Arduino IDE › Tools › Serial Monitor (set line ending to "No line ending")
-3. On the device, navigate to **Tools › Trail**, then **Hold Enter** and select **Export GPX** (live ring) or **Export saved** (flash slot).
-4. The device streams a GPX 1.1 XML document to the serial port. Copy the output starting from `<?xml` to `</gpx>` and save it as a `.gpx` file.
-5. Import the file into any GPX-compatible application — OsmAnd, Garmin BaseCamp, GPX Studio, Google Earth, etc.
-
-> **Note:** If the companion app is connected over **BLE**, the export is safe — the app ignores USB input while BLE is active and the device alert will read *"GPX N B (USB)"*. If you are using the app over **USB**, disconnect from the app first before exporting; the raw XML stream will otherwise disrupt the app's serial framing. The alert *"GPX N B - disc. app"* indicates no BLE link was detected and serves as a reminder to reconnect the app afterwards.
-
-#### Auto-Advert
-
-Periodically broadcasts a 0-hop advert with your GPS position so nearby nodes can track your location automatically. Configurable interval: off / 30 s / 1 min / 2 min / 5 min / 10 min / 30 min / 1 h.
-
-A blinking **A** indicator appears in the status bar while Auto-Advert is active.
-
-#### Ringtone Editor
-
-A step sequencer for composing custom notification melodies stored on the device. Two independent melody slots are available — **Melody 1** and **Melody 2** — switchable from within the editor. Each melody supports up to 32 notes with adjustable pitch (C–B + pause), octave (4–7), duration (1/4 / 1/8 / 1/16 / 1/32), and BPM (60 / 90 / 120 / 150 / 180). Playback preview is available directly from the editor.
-
-Melodies can be assigned as notification sounds per message type (DM / channel) in Settings, and individually overridden per channel or per contact from the message screen context menu.
-
-#### Auto-Reply Bot
-
-Automatically replies to incoming messages that contain a configured trigger word (case-insensitive).
-
-- **DM mode** — when enabled, the bot listens to all incoming private messages and replies with the DM reply text.
-- **Channel mode** — optionally, select a channel for the bot to monitor. When a trigger is matched, it replies with a separate channel reply text.
-- Both modes can be active simultaneously and share the same trigger word but use independent reply texts.
-- Replies support placeholders (`{time}`, `{loc}`).
-- A 10-second cooldown prevents repeated replies in quick succession.

+Screen lock prevents accidental keypresses. While locked the display turns off and all input is ignored.
+
+---
+
+### Locking and unlocking
+
+**Hold Back** and press **Enter** three times within 3 seconds. The sequence works in both directions — the same combination locks and unlocks.
+
+If the display is off when the sequence begins, it turns on automatically so the hint is visible. Each press in the sequence extends the display-on timer by 5 seconds.
+
+The hint popup at the bottom of the lock screen guides through the sequence:
+
+| Step           | Hint                  |
+| -------------- | --------------------- |
+| Not started    | _Hold Back + 3×Enter_ |
+| 1 press done   | _Enter ×2 more…_      |
+| 2 presses done | _Enter ×1 more…_      |
+
+If no press is made for 3 seconds, the counter resets.

+
+A brief press of any button wakes the display and shows the lock screen. It displays:
+
+- **Time** — large, same format as the Clock page (24 h / 12 h from Settings)
+- **Date** — day-of-week, day, month
+- **Two sensor values** — the first two Dashboard Config fields (same values configured for the Clock page); shown side by side if both are set
+
+The display turns off again automatically after 5 seconds of inactivity (or 2 seconds immediately after locking).
+
+---
+
+### Auto-lock
+
+Enable **Auto-lock** in **Settings › Display** to lock the device automatically whenever the display turns off due to auto-off timeout. With auto-lock on, the device is always locked after the screen goes dark — no manual lock needed.

+## Tools Screen
+
+[Go back](../../../README.md)
+
+### Overview
+
+|           OLED            |           E-Ink           |
+| :-----------------------: | :-----------------------: |
+| ![](./tls_scr_1_oled.png) | ![](./tls_scr_1_eink.png) |
+
+The Tools screen is a hub for GPS trail recording, nearby node browsing, ringtone editing, auto-reply bot, and auto-advert. Navigate the tool list with **UP/DOWN** and press **Enter** to open a tool.
+
+---
+
+## Nearby Nodes
+
+|           OLED            |           E-Ink           |
+| :-----------------------: | :-----------------------: |
+| ![](./tls_scr_2_oled.png) | ![](./tls_scr_2_eink.png) |
+
+Browse nodes that have recently advertised on the mesh. Filter by category with **LEFT/RIGHT**:
+
+| Filter | Shows                          |
+| ------ | ------------------------------ |
+| Fav    | Upstream-starred contacts only |
+| ALL    | All known nodes                |
+| Comp   | Companion (chat) nodes         |
+| Rpt    | Repeaters                      |
+| Room   | Room servers                   |
+| Snsr   | Sensors                        |
+
+Select a node to see its coordinates, distance, bearing with cardinal direction, type, and last-heard time.
+
+**Hold Enter** → context menu → **Discover nearby** to send a live `NODE_DISCOVER_REQ` ping.
+
+> [!TIP]
+> Combined with **Auto-Advert** on the other device, Nearby Nodes becomes a passive location tracker — as long as the tracked device periodically broadcasts its GPS position, you can see its current distance and bearing without any manual interaction on either end.

+
+Records your route in a RAM ring buffer (up to 512 points, sampled every 1 s). Tracking runs in the background — a blinking **G** appears in the status bar. The trail survives display auto-off but is lost on reboot unless saved to flash first.
+
+Cycle views with **LEFT / RIGHT**:
+
+| View        | Content                                                                                                                                                             |

+
+### Downloading GPX
+
+1. Connect the device via USB cable
+2. Open a serial terminal at **115200 baud**:
+   - **macOS/Linux** — `cat /dev/tty.usbmodem* > track.gpx` (stop with Ctrl-C after dump completes)
+   - **Windows** — PuTTY (Serial, 115200) or Arduino IDE Serial Monitor (no line ending)
+3. On the device: **Tools › Trail** → **Hold Enter** → **Export (live)** or **Export (saved)**
+4. The device streams a GPX 1.1 XML document. Save the output from `<?xml` to `</gpx>` as a `.gpx` file
+5. Import into OsmAnd, Garmin BaseCamp, GPX Studio, Google Earth, etc.
+
+> [!NOTE]
+> If the companion app is connected via **BLE**, the export is safe — BLE and USB operate independently. If connected via **USB**, disconnect the app before exporting.
+
+---
+
+## Auto-Advert
+
+Periodically broadcasts a 0-hop advert with your GPS position. Configurable interval: off / 30 s / 1 min / 2 min / 5 min / 10 min / 30 min / 1 h. A blinking **A** appears in the status bar while active.
+
+---
+
+## Ringtone Editor

+| :-----------------------: | :-----------------------: |
+| ![](./tls_scr_6_oled.png) | ![](./tls_scr_6_eink.png) |
+
+A step sequencer for composing custom notification melodies. Two slots — **Melody 1** and **Melody 2** — switchable from within the editor.
+
+Each melody supports up to 32 notes:
+
+| Parameter | Options                           |
+| --------- | --------------------------------- |
+| Pitch     | C / D / E / F / G / A / B / pause |

+| BPM       | 60 / 90 / 120 / 150 / 180         |
+
+**Navigation in the editor:**
+
+- **LEFT/RIGHT** — move between notes
+- **UP/DOWN** — change pitch of selected note
+- **Enter** — cycle octave of selected note
+- **Hold Enter** (or context menu) — open options menu
+
+**Options menu:**
+
+| Item         | Interaction | Action                                 |
+| ------------ | ----------- | -------------------------------------- |
+| Play / Stop  | Enter       | Preview the melody                     |
+| Melody 1 / 2 | Enter       | Switch to the other slot               |
+| Duration     | LEFT/RIGHT  | Cycle duration for selected note       |
+| BPM          | LEFT/RIGHT  | Cycle tempo                            |
+| Insert       | Enter       | Insert a new note after the cursor     |
+| Delete       | Enter       | Delete the note at cursor              |
+| Save & Exit  | Enter       | Persist the melody and return to Tools |
+| Discard      | Enter       | Return to Tools without saving         |
+
+Melodies can be assigned in **Settings › Sound** (global default) or overridden per contact or channel from the Messages screen context menu.

+## Auto-Reply Bot
+
+|           OLED            |           E-Ink           |
+| :-----------------------: | :-----------------------: |
+| ![](./tls_scr_7_oled.png) | ![](./tls_scr_7_eink.png) |
+
+Automatically replies to incoming messages that contain a configured trigger word (case-insensitive, contains match).
+
+When the bot is enabled it listens to DMs by default. Channel monitoring is an optional addition — select a channel separately to activate it alongside DM mode.
+
+| Setting       | Description                                                                      |
+| ------------- | -------------------------------------------------------------------------------- |
+| Bot           | ON / OFF — enables DM listening                                                  |
+| Channel mode  | ON / OFF — additionally monitors a selected channel                              |
+| Channel       | Which channel to monitor (only relevant when channel mode is ON)                 |
+| Trigger       | Word or phrase that activates the reply (shared by both modes, case-insensitive) |
+| DM reply      | Reply text for DMs; supports `{time}` and `{loc}` placeholders                   |
+| Channel reply | Reply text for channel messages; supports `{time}` and `{loc}` placeholders      |
+
+A 10-second cooldown prevents repeated replies in quick succession.
