avea.Bulb.get_rgb() returns a 3-tuple of integer RGB values by contract. I do not plan to add a guard here unless you want explicit validation despite that contract.

The reason is that applying a fresh brightness value while skipping a failed color refresh would publish mixed-freshness state, which is the inconsistency this bugfix is trying to avoid. If the RGB read/conversion unexpectedly fails, failing the whole refresh is preferable to updating only part of the light state.

This is the same concern as the earlier RGB thread. I am keeping the production code unchanged here because avea.Bulb.get_rgb() returns an RGB 3-tuple by contract, including when it falls back to cached values after a failed connection attempt.

The failed pre-connect fallback path is now covered by test, so we verify that brightness and color are both still applied from the returned cached values. Adding a guard that skips only color would allow mixed-freshness state, which this PR is trying to avoid.
