Hold — do not merge yet.

Maintainer request: do not cut v3.0.0 until dogfooding / testing of the 2.x→3.x delta is complete (climate, dual energy, entity IDs, library ≥0.8.0).

Use dev RCs (dev-v3.0.0-rc.* or current dev-v2.1.0-rc.* naming until the next version bump lands) for testing. Merge this release-please PR only when explicitly ready to publish stable 3.0.0 to HACS.
