When 'esphome logs' processes a crash backtrace from the device,
process_stacktrace -> _decode_pc -> _run_idedata can raise
EsphomeError if the local build dir hasn't been populated (e.g. the
device was flashed from a different machine). on_log runs inside an
asyncio protocol callback, so the unhandled exception triggers
'Fatal error: protocol.data_received() call failed.', the loop tears
the connection down, and ReconnectLogic immediately reconnects. The
device replays the same crash trace and we loop forever.
Wrap the per-line decode in a helper that swallows EsphomeError so
the connection stays up. Also covered with unit tests for the new
helper.
