merge: resolve conflicts with main, document IDisposable patterns

Resolve merge conflicts from main:
- dotnet/src/Session.cs: Integrate SetModelAsync, simplified permission cleanup
- python/copilot/client.py: Adopt ExceptionGroup-based stop() error handling
- python/e2e/test_client.py: Update to ExceptionGroup test pattern

Document IDisposable/cleanup patterns across all SDKs:
- .NET: Class-level XML docs explain IAsyncDisposable contract, README documents
  DisconnectAsync + DisposeAsync with await using examples
- Python: README documents async with context manager pattern
- Node.js: README documents Symbol.asyncDispose / await using pattern
- Session persistence guide: Add cross-SDK cleanup pattern comparison table

Update new files from main (tool-overrides scenario, streaming fidelity tests)
to use disconnect()/Disconnect() instead of destroy()/Destroy().
