refactor(core): Native AOT - JSON source generators, AOT-safe models and API client

- Add NozJsonContext / NozJsonContextPretty source generator contexts
- Replace all reflection-based JSON with source-generated overloads
- Add NotesCacheFile record for persistent note cache
- Add date field to NoteInfo, CancellationToken to all API methods
- LocalConfig uses source-generated serialization (compact + indented)
