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.
The contact sync streams up to MAX_CONTACTS frames back to back, but
ArduinoSerialInterface never checked whether the stream could take
them: isWriteBusy() returned false unconditionally, so MyMesh's pacing
gate had no effect, and writeFrame() called write() without looking at
availableForWrite(). On ESP32 (HWCDC, 256 byte TX ring) a host that
stalls for a moment makes the driver drop queued bytes silently, which
tears a frame in half - and since the framing is length prefixed with
no checksum and no resync marker, the client stays desynchronised for
the rest of the session. Reported as 'the app disconnects while
syncing contacts' on devices with a large contact list.
Add opt-in flow control: report busy until a whole frame fits, and
drop frames as a unit instead of tearing them. Enable it for the
companion USB interface and give HWCDC a bigger TX buffer with a short
write timeout, mirroring what kiss_modem already does.

ArduinoSerialInterface::isConnected() always returned true, so any
companion build with a USB interface believes a client is attached from
boot onwards. Two user visible effects:
- new message notifications never fire, because MyMesh only notifies
the UI (display, buzzer) while no client is connected
- on builds that also expose BLE the home screen shows '< Connected >'
instead of the BLE pairing PIN, so a freshly flashed device cannot be
paired at all
Add an optional connection check callback and wire it up per platform:
native USB-CDC (TinyUSB on nRF52/RP2040/ESP32 with USB_MODE=0) exposes
real DTR through (bool)Serial. The ESP32 USB-Serial-JTAG peripheral has
no DTR concept - it reports 'connected' as soon as the host enumerated
the device - so fall back to frame activity there. Plain UARTs keep the
previous assume-connected behaviour.

If an `ota pull <#> folder` block-write fails mid-transfer (the motatool seeder
link dropped), the fetch enters a new PAUSED state instead of failing or falling
back to RAM/flash: progress stays on the host, the manager stops requesting, and
loop()/stall-detection leave it untouched (it waits indefinitely). On reconnect
the ESP32 seeder re-registers the folder destination and, if PAUSED, calls
resumeStaged(): OP_STAT re-attaches the host's partial, the leaves are re-read,
and only the missing blocks are re-requested (a brand-new/absent file restarts
from 0). `ota status` reports the paused state.
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.
The discovery beacon previously re-announced at a random 3-10 min interval.
Replace that with a fixed, user-configurable cadence:
- OtaManager::advert_mins() — re-advertise every N minutes after the boot
burst; 0 disables periodic re-advertise (boot burst only). Default 24h.
- Persisted in NodePrefs (CommonCLI) and runtime-tunable: `ota config advert
<minutes>` (0..10080; 0 = off), and shown in `ota config`.
- When periodic advert is disabled, the scheduler still re-checks the config
on a slow timer, so a later `ota config advert <mins>` takes effect live.
Also advertise immediately whenever the served set changes — when a motatool
folder is attached to / detached from the ESP32 WiFi seeder — so peers learn
about newly-available firmware without waiting for the next interval (the
`ota folder` serial path already announced on attach).
Docs: protocol beacon-cadence note + user-guide `ota config advert`.
Extends the USB-serial folder relay to WiFi so an ESP32 companion can both
serve .mota and be operated headlessly:
- motatool `serve --tcp <host[:port]>`: a TcpTransport sibling of the serial
transport (default port 5001). SeederCore/Folder are reused unchanged — the
COUNT/DESCRIBE/READ protocol is transport-agnostic.
- ESP32 companion: a dedicated OTA seeder port (5001) for `serve --tcp`, plus
an OTA text console on 5002 (`nc <ip> 5002` -> `ota status|ls|announce|...`,
the same handle_ota_command CLI serial nodes have). Both run alongside the
phone-app port (5000); all three coexist.
- WiFi.setSleep(false): ESP32 STA mode's modem power-save periodically sleeps
the modem/CPU and stalls the SX1262 SPI+DIO servicing, leaving LoRa deaf
while WiFi is associated. Disabling it restores the radio (HW-validated:
a V3 WiFi companion is then discovered over LoRa and discovers its peers).
