v0.1.2

Per-grow-space AI health entities.

Changed

• AI health entities are now per grow space. Score, summary, feeding schedule, last check, critical alert, and the run button are attached to each grow-space device and named per tent (e.g. sensor.3x3_mothers_tent_ai_health_score) instead of the global sensor.ai_health_score / _2.
• Automatic id migration: on setup, legacy auto-generated ids migrate to per-space ids. User-customized entity ids are left untouched, and migration is collision-safe and idempotent.

Upgrade notes

• After updating in HACS, restart Home Assistant; the ids migrate on setup.
• Update any of your own dashboards/automations that referenced the old ids. The bundled dashboards/tendrial_grow.yaml example is already updated - re-import it via the dashboard's Raw configuration editor.
• 83 tests passing; ruff clean.
