CI / build + unit (pull_request) Failing after 22s
The v0.21.2 frame-based watchdog works in production (it fired today: 'no decoded bridge frames for 628474 ms — forcing reconnect', and the reconnect delivered queued packets), but the bridge/radio side at 192.168.1.4 keeps killing inbound RX within ~20 min of a fresh sync, repeatedly. Two tuning changes requested by the owner: - MESH_IDLE_TIMEOUT_MS default lowered from 600000 (10 min) to 60000 (1 min). - New lazy periodic autoreconnect: MESH_RECONNECT_INTERVAL_MS (new env, default 300000 = 5 min, read at construction like the others). An interval started in onModuleInit unconditionally logs and destroys the socket so the existing close -> scheduleReconnect loop re-establishes with a fresh sync on schedule; cleared in onModuleDestroy. When not connected at tick time, destroy is a no-op and the retry loop owns recovery — no special-casing. Tests: 171 -> 172 — periodic reconnect observed end-to-end with an overridden short interval (fake bridge disconnect + re-establish); existing watchdog tests pass unchanged, comments updated to the new 60 s default.
