- Add SqliteForeignKeyInterceptor (DbConnectionInterceptor) registered via
OnConfiguring so every IDbContextFactory-created context runs
PRAGMA foreign_keys=ON, not only the MigrateAndConfigure context.
- DefaultListsSeeder: replace TOCTOU read-then-insert with atomic
INSERT … SELECT … WHERE NOT EXISTS — one SQLite writer lock, no race.
- AppSettingsRepository.GetAsync: catch DbUpdateException on the
get-or-create path and re-read so concurrent startup cannot throw.
- Migration 20260609000000_UniqueListName: de-duplicates empty list rows
(startup-race leftovers) then adds a UNIQUE index on lists.name.
- ForeignKeyTests: verifies ON DELETE SET NULL (blocked_by_task_id) is
enforced on a fresh DbContext with no manual PRAGMA call.

list_task_lists returns two different ID formats: dashed UUIDs (e.g. "caed660e-109f-4e2a-b055-2c2722bf6fb7") and compact 32-char hex (e.g. "5c2cafcb33f044069ac324ac3fd84a16"). Mixing formats makes equality checks, logging, and lookups error-prone.
Fix: pick one canonical format (recommend dashed UUID) and normalize on write + migrate existing records. Ensure all ID-returning tools emit the same f
