`_read_json_file` caught OSError but not UnicodeDecodeError, so a status file holding binary/non-UTF-8 bytes (truncated or clobbered write) would crash the gateway status path instead of being treated as unreadable. UnicodeDecodeError is a ValueError subclass, not an OSError, so it escaped the existing guard. Widen the catch to (OSError, UnicodeDecodeError) at both read sites in gateway/status.py — `_read_json_file` and the sibling `_read_pid_record`, which had the identical gap. Adds tests covering binary input (returns None) and valid input (still parses) for both. Co-authored-by: Teknium <127238744+teknium1@users.noreply.github.com>
