Implements task 473f65aa (Feature 02, task 3 of 4).

Done-condition: migrations/0001_init.sql creates every table in the CTXD data model (25 tables) with foreign keys, CHECK constraints for every enum column (dinners.status and notification_prefs.event rotation_review named), unique constraints on the eight named keys; tests assert each table exists, each enum CHECK rejects an invalid value, each unique constraint rejects a duplicate, and deleting a parent with children is refused. Go quality floor passes.

Evidence (developer-run, to be re-verified at review): gofmt -l . empty; go vet ./... clean; go test -race -count=1 ./... ok (internal/store 83 tests/subtests); CGO_ENABLED=0 go build ./... ok; real boot against a temp data dir recorded 0000_bootstrap,0001_init and 25 tables.

Base: feature/b9c21d67-...-sqlite-data-layer-and-schema (b06d168).

Add initial v1 schema migration ... 50b670e0a8

migrations/0001_init.sql creates the 25 tables of the CTXD CONTEXT.MD data
model with foreign keys (default NO ACTION, so a parent with children cannot
be deleted; ai_run_id references are ON DELETE SET NULL for the 30-day
ai_runs purge), a CHECK on every enum and boolean column, and the unique
constraints the model names. Single-row settings tables are pinned to id 1.

internal/store/schema_test.go migrates a temp database with the embedded
migrations and asserts every table exists, every enum CHECK rejects an
invalid value, every named unique constraint rejects a duplicate, and
deleting a parent with children is refused.

TestMigrateEmbeddedMigrations now expects 0000_bootstrap,0001_init, and the
upgrade test migrates a bootstrap-only database to the real embedded set.

Tighten v1 schema keys, weekday checks and ai_runs references ... 7b760e87b1

- ai_run_id in suggestion_batches and week_plans now uses the default
  refusing action instead of ON DELETE SET NULL; the ai_runs purge must
  clear references explicitly. Tested as a refused parent delete.
- Every TEXT primary key (including notification_prefs.event and
  sessions.id_hash) is NOT NULL; tested that NULL keys are rejected.
- Weekday columns use CHECK (col IN (0, 1, 2, 3, 4, 5, 6)) so fractional
  values are refused; tested with 5.5, 0.5 and 3.5.
- Composite UNIQUE tests add positive partial-overlap cases (same date
  under different plans, same plan_date for different dinners, same
  event_key on different channels, same period_key for different
  schedules).
