feat(persist): Phase 2 — SQLite backend with WAL mode
...
Add multi-process safe SQLite persistence using modernc.org/sqlite (pure
Go, no CGO). Follows the go-store pattern: single connection,
WAL journal mode, 5-second busy timeout.
New files:
- sqlite.go: sqliteStore with schema (quotas, requests, tokens, daily
tables), saveQuotas/loadQuotas, saveState/loadState, close methods
- sqlite_test.go: 25 tests covering basic round-trips, integration,
concurrency (10 goroutines, race-clean), migration, corrupt DB recovery
Wiring:
- Backend field added to Config ("yaml" default, "sqlite" option)
- Persist() and Load() dispatch to correct backend
- NewWithSQLite() and NewWithSQLiteConfig() convenience constructors
- Close() method for cleanup (no-op for YAML)
- MigrateYAMLToSQLite() helper for upgrading existing YAML state
All existing YAML tests pass unchanged (backward compatible).
