Extends the plants store (which had only the /full read side) with full
catalog CRUD, adds a service layer with visibility/immutability rules, REST
endpoints, and a seed migration of ~32 built-ins.
- 0003_seed_plants.sql: 32 built-in plants (owner_id NULL, read-only), seeded
once by the version-tracked migration runner.
- store: ListPlantsForActor (built-ins + own), Get/Create/Update/Delete +
CountPlantingsForPlant; isForeignKeyViolation backstop for the RESTRICT FK.
- service: built-ins are read-only (ErrForbidden); another user's plants are
invisible (ErrNotFound); delete of a referenced plant → ErrPlantInUse (409);
validation mirrors the schema (category enum, spacing>0, hex color, icon).
- api: GET,POST /plants and PATCH,DELETE /plants/:id with the version guard.
- Made the migration-count store tests derive their expectation from the files
so future migrations don't break them.
Service + API tests cover visibility, built-in immutability, validation,
version conflict, and delete-in-use.
