liquidraver 38f815a0a1 server roles, event loops, companion transports, storage and prefs.json
Server roles (slice 7)
- CommonCLI split into upstream's shape; region CLI moved into CommonCLI;
  ClientACL, RegionMap, TransportKeyStore and both server meshes in
  upstream shape over an Arduino compat shim (helpers/compat: Arduino.h,
  Stream/Print, Serial, SHA256, FILESYSTEM/File over Zephyr fs)
- room server processAck port; `get acl` prints as upstream
- room: default name Room-XXXX, display/input rotation, live radio UI refresh

Event loops (slice 7b)
- repeater and room server share server_main_common with a ServerRole
  descriptor; shared event bits in src/mesh_events.h
- room server deadline-driven (idle wakes 2.2/s -> 0.08/s); companion
  loop() runs on housekeeping (closes the lazy contact-flush gap)
- `get loop.wakes` in debug builds (CONFIG_ZEPHCORE_LOOP_WAKE_STATS)

Companion transports and WiFi (slice 8)
- upstream MultiSerialInterface: BLE, USB/UART and TCP are each a
  BaseSerialInterface, every connected transport gets every frame;
  CompanionSerial holds a lossless reply; shared frame_txq for BLE/TCP
- SerialCompanionTransport and LinuxTCPTransport replaced by
  TcpCompanionTransport; ZephyrBLE split (gatt layout, DFU)
- WiFi companion (upstream wifi.ssid/pwd/enabled CLI, TCP port 5000) on
  boards declaring `capabilities: wifi` in zephcore.yml: the PSRAM
  ESP32-S3 boards, plus Heltec V3 (140 contacts), Wireless Tracker (130)
  and both C6 boards (280); ESP32-S3 without PSRAM gets bounded WiFi
  buffers and a measured 72 KB heap; PSRAM boards' internal heap 72 KB
- TCP queues: own depth (ZEPHCORE_TCP_QUEUE_SIZE=8), RX waits instead
  of dropping
- RAM: companion ClientACL dropped; main/BT-TX/TCP stacks sized from
  measured peaks (-7 KB nRF companions, -9 KB ESP32 companions)
- ESP32 WiFi stopped working under ~200 frames/s unicast. Fixed by:
  patches/zephyr/0017 never block the WiFi task in the RX callback;
  patches/zephyr/0018 lock shared_multi_heap (heap corruption with the
  WiFi heap in PSRAM); patches/modules/hal_espressif/0001 backport of
  hal_espressif af97fb02df (PSRAM realloc)

Storage and prefs (slice 9)
- prefs are now prefs.json through upstream's ConfigSerializer (ported
  verbatim), with upstream's key names for shared fields and ZephCore's
  own under "zc"; on first boot the binary new_prefs / repeater prefs is
  migrated and kept, so a downgrade still boots with the old settings
- helpers/PrefsCodec: both legacy binary layouts (companion 272 B,
  server 311 B) as Zephyr-free codecs; sanitizeNodePrefs is the only
  validator
- fix: server prefs could be replaced by a truncated file when a write
  failed; identity, prefs and channel writes go through one checked
  atomic replace (ZephyrFsUtil)
- fix: a corrupt cad_auto byte turned adaptive CAD off instead of the
  default on
- fix: a deliberate 300 s GPS duty on a repeater was rewritten to 48 h
  on every boot (that migration now runs on legacy files only)
- one identity loader for all roles (IdentityFile); an unusable key
  file is always parked as .bad before regenerating
- server store no longer stamps repeater defaults on room server and
  observer; companion first-boot volume policy moved into the store
  (adoptVolume)
- ZephyrDataStore 1435 -> ~850 lines
