G1: F06 — wrap handle_rx dispatch in catch-all try/except

Browse source

Why: handle_rx is invoked from a detached task in MessageReader, so any
exception escaping its ~850-line if/elif dispatch is silently swallowed
by asyncio as "Task exception was never retrieved." The only crash
guard previously was a single try/except IndexError around the first
byte read; everything past line 73 was unguarded. This commit adds an
umbrella try: ... except Exception as e: around the entire dispatch
body that logs the exception class, message, raw frame hex, and full
traceback via logger.error. The umbrella neutralizes the crash surface
of F10, F11, N07, N08, R01, NEW-B, and NEW-C, which the next commits
will then fix individually now that they are observable.
