Replace JSON file-based session storage with SQLite backend while maintaining full backward compatibility through LegacyAdapter. New files: - pkg/session/types.go: Turn, SessionInfo, CreateOpts, ListFilter types - pkg/session/store.go: SessionStore interface (15 methods) - pkg/session/sqlite.go: SQLite implementation (WAL mode, modernc.org/sqlite) - pkg/session/legacy_adapter.go: wraps SessionStore with SessionManager API - pkg/session/migrate.go: JSON → SQLite migration at startup Changes: - pkg/agent/instance.go: Sessions type changed to *LegacyAdapter - loop.go / loop_test.go: zero changes (method signatures identical) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
