Dispatcher's default 4-second getCADFailMaxDuration() would trigger
forced transmission before JP LBT backoff completes (max 16s), violating
ARIB STD-T108 which prohibits TX while channel is busy.
- Add isJapanMode() virtual method to Radio base class (Dispatcher.h)
- Override getCADFailMaxDuration() in all Mesh subclasses to return
UINT32_MAX in Japan mode — no forced TX, channel must be free
- Default non-JP behavior unchanged (4000ms)
If ambient noise exceeds -80dBm, TX is blocked indefinitely. Users can
monitor noise floor via companion app: menu (⋮) -> Tools -> Noise Floor.
* room server: added RegionMap, and new CommonCLI wiring, default_scope handling
* sensor: only minimal RegionMap wiring. Still needs work to handle default-scope
- Added formatStatsReply, formatRadioStatsReply, and formatPacketStatsReply methods in MyMesh for both simple_repeater, simple_room_server, and simple_sensor.
- Updated CommonCLI to handle new stats commands.
