The solo release job only attached *.uf2 and *.zip, which covered every solo
board back when they were all nRF52. The Heltec V3/V4 .bin images were built
and then silently dropped, so tagging a release produced nothing downloadable
for those two boards.
Releases now carry a single -merged.bin per ESP32 board (bootloader +
partition table + app at 0x0). build.sh also writes an app-only .bin, but
that one needs offset 0x10000 and a bootloader already on the chip, so it's
deleted before upload rather than shipped next to the merged image — flashing
it at 0x0 looks exactly like a bricked device.
Also adds -D ENABLE_SCREENSHOT to both Heltec solo envs. Every other solo env
already had it, so Solo Tools couldn't capture these two boards' displays and
the README's "no special build flags required" was untrue for them. Both envs
rebuilt clean (V3: RAM 58.8%, Flash 43.2%).

Port the Wio Tracker L1 solo firmware (full on-device UI, dual BLE/USB
companion transport) to Heltec V3 and V4 OLED boards. Neither board has
a joystick or CardKB on-board, so each new env wires up both as optional
peripherals with default pins from what the board leaves free, gated
behind the existing UI_HAS_JOYSTICK/ENV_PIN_SDA+SCL flags.
DUAL_SERIAL was nRF52-only; added an ESP32 helpers/esp32/DualSerialInterface.h
counterpart so the flag isn't silently ignored on these boards. On V4's
native USB CDC, isClientConnected() also honours (bool)Serial (real DTR),
same as the nRF52 version; V3 has no native CDC so it stays BLE-only there.
Screen (SDA 17/SCL 18) and CardKB (SDA 3/SCL 4) confirmed working on real
V4 hardware.

Enable GPS time synchronization across all variants by passing
&rtc_clock to MicroNMEALocationProvider. When GPS gets a valid
fix, the RTC clock is now updated automatically every 30 minutes.
Updated 16 variants: rak4631, lilygo_tbeam_SX1262, rak_wismesh_tag,
lilygo_tbeam_supreme_SX1262, thinknode_m3, heltec_v4, thinknode_m1,
lilygo_tbeam_SX1276, meshadventurer, nano_g2_ultra, heltec_v3,
promicro, xiao_c3, heltec_tracker_v2, keepteen_lt1, heltec_mesh_solar.
The GC1109 FEM needs its VFEM_Ctrl pin held HIGH during deep sleep
to keep the LNA active, enabling proper RX sensitivity for
wake-on-packet. Without this, the LNA is unpowered during sleep
and RX wake sensitivity is degraded by ~17dB.
Release RTC holds in begin() after configuring GPIO registers
(not before) to ensure glitch-free pin transitions on wake.
Trade-off: ~6.5mA additional sleep current for significantly
improved wake-on-packet range.
