Review comments at @fbclient/streaming.py:
- Around line 318-319: In `fbclient/streaming.py` lines 318-319, restore the
reconnect path when `_on_process_data` returns `False` so failed sync
application triggers recovery instead of leaving the connection open. In
`tests/test_runtime_safety.py` lines 547-550, update the assertion to verify
that failure starts recovery rather than preserving the same connection.
- Line 308: Update the message handling path around the data-sync check so only
pong messages return early; route invalid JSON, malformed processing data, and
invalid data-sync payloads through the existing data-invalid close path. In
tests/test_runtime_safety.py lines 494-497 and 523-527, assert that invalid
non-pong shapes, invalid JSON, and invalid data-sync payloads close the stream
with a data-invalid state.
