Add SessionFs sqlite support for runtime sqlite routing

Update SDK to support the new sqlite() method on SessionFs, allowing
SDK apps to intercept per-session SQLite operations.

Key changes:
- SessionFsProvider.sqlite() accepts queryType parameter
- SessionFsSqliteQueryType exported from all entry points
- handleSqlite flag on SessionFsConfig
- Regenerated types for all language SDKs (Node, Python, Go, C#, Rust)
- E2E test for sqlite round-trip with queryType dispatch
