Add the framed BLE mOTA transport and companion control path, complete the full-profile build and runtime fixes, and document and test the OTA workflow.
Expose the Full Companion terminal over TCP and add an authenticated, replay-resistant host command service with documented CPU temperature, reboot, and allowlisted program examples.\n\nImprove LoRa OTA diagnostics and persistent CLI handling, reduce clock correction drift to ten minutes, and make mOTA stream flush behavior an explicit transport policy with regression coverage.
FolderMotaStore: an OtaStore that streams an in-transit .mota straight to the host
folder over the seeder link (OP_BEGIN/WRITE/SREAD/STAT/FIN) instead of RAM/flash —
the device holds no local staging for it. Wired as a selectable pull destination:
- OtaContext gains a folder_dest (registered by the app while a motatool `serve`
link is up) + its human id (e.g. "tcp 192.168.4.5").
- `ota pull <#> <dest>` now takes a MANDATORY destination; `ota pull <#>` with none
lists the choices (flash always; folder + its link id when connected).
- The ESP32 WiFi seeder registers/clears the folder destination on connect/close —
the same connection both serves the folder and accepts pulls into it.
Captures an exact copy of a device's firmware over the mesh to build a delta
against. Pause/resume on a mid-pull disconnect follows.
