feat(KB-310): migrate storage layer to SQLite with WAL mode and auto-migration

- Add SQLite database foundation with WAL mode, transactions, and JSON column helpers
- Implement auto-migration system from legacy file-based storage with .bak backup strategy
- Migrate TaskStore to SQLite with full test coverage (256 tests)
- Migrate AutomationStore to SQLite with full test coverage (48 tests)
- Add SQLite Storage Architecture documentation to AGENTS.md
- Include changeset for patch release
