Address the open items from the FEATURES.md audit backlog:
- saveChannels() now skips unused slots (all-zero secret) instead of
writing all 40 every time, so /channels2 holds only configured channels
(was always ~2.7 KB) and wears the flash less. loadChannels() already
compacted empties on read, so the loaded result is unchanged.
- findChannelIdx() returns -1 for an all-zero secret, so a corrupted/empty
channel can't match an unused all-zero slot and misroute messages.
- TrailStore gains a static_assert that CAPACITY fits the uint16_t save
header count, failing the build instead of silently truncating.
Also re-classify two audit items verified to be non-issues in current
code: the bot strstr "199-char" truncation (BOT_SCRATCH=200 >= MAX_TEXT_LEN
=160, unreachable) and the MSG_PICK reply title (rlen clamped to 20, so
title[24] never overflows).
Verified: WioTrackerL1_companion_solo_dual builds clean.

Reverts onDiscoveredContact to the upstream 4-param signature, adding a
separate virtual onDiscoveredAdvert(bool was_flood) with a default no-op
implementation. Only MyMesh overrides the new virtual; simple_secure_chat
and any future implementors need no changes on upstream merges.

- Change > to >= so stored value 1 means direct/0-hop only (liamcottle)
- Clamp max_hops to 63 on write since getPathHashCount() caps at 63 (robekl)
- Update comments to reflect encoding: 0=no limit, 1=direct only, N=up to N-1 hops

Filter auto-add of new contacts by hop count (issues #1533, #1546).
Setting is configurable from the companion app via extended
CMD_SET/GET_AUTOADD_CONFIG protocol (0 = no limit, 1-63 = max hops).

* BasChatMesh: new onContactRequest(), for PAYLOAD_TYPE_REQ handling.
* companion, repeater and room_server: now with basic 'plumbing' to handle REQ_TYPE_GET_TELEMETRY_DATA (0x03).
* dependency: added CayenneLPP to libdeps
* all target.* modules now with a stub 'sensors' object.
