v0.10.0: ports and adapters refactor

- Extract shared manifest types into internal/manifest/types leaf package.
- Extract SQLite adapter into internal/manifest/sqlite.
- Extract JSONL adapter into internal/manifest/jsonl.
- Isolate modernc.org/sqlite import to sqlite/adapter.go.
- Add adapter-backed registry with manifest.Default.
- Adapter-agnostic ConvertManifest in types/.
- MemoryAdapter for in-memory manifest testing.
- CLI uses manifest.Default registry directly.
- SQLite LogWriter type assertion moved into SQLiteAdapter.
- Manifest interface includes Entries(); EntryReader removed.
- No behavior changes. 100% coverage across all 6 packages.
