sauravpanda ea99055e53 fix: write config.json atomically via tmp+rename to prevent silent data loss ...

A SIGKILL mid-write truncates config.json; read_config() catches
json.JSONDecodeError and returns {}, silently wiping the API key and
all other settings. Mirror the pattern already used by _write_state():
write to a sibling temp file, fsync, chmod 600, then os.replace() into
place — which is atomic on POSIX and effectively atomic on Windows.
