v0.1.3

Fixes multiple-vehicle support.

🐞 Bug fixes

• Multiple vehicles now expose all entities (#7). Raw diagnostic sensors used the bare dataset key as their unique_id, but those keys are shared across vehicles — so with more than one car configured, the entity registry rejected the second entry's colliding entities and each data point appeared under only one car (split arbitrarily). Raw unique_ids are now namespaced by VIN. (8b4b43e)

⬆️ Upgrade notes

• A one-time entity-registry migration renames legacy raw-sensor IDs (<key> → <vin>_<key>) on first start after upgrading, so existing single-vehicle installs keep their entity IDs and customisations — no manual cleanup needed.
• Curated sensors were already VIN-namespaced and are unaffected.
