Add bounded Morse receive and negotiated RS232 autosleep
Add native narrow-band CW capture, ACK-first remote sessions, retained LoRa-readable pages, checked restoration and transport-safe progress. Add stock-compatible negotiated heartbeat/autosleep and recovery. Include host regressions and identity-bound HIL runners; keep unverified faster tuning HIL-only and document outstanding hardware validation.
