* docs: prepare v0.1.0 release with documentation updates and cleanup

Update documentation to reflect recent refactoring and current metrics:
- Finalize CHANGELOG.md for v0.1.0 release (2025-10-06)
- Add recent refactoring entries (try-except wrappers, transformation_service, TypedDicts)
- Update architecture.md: remove transformation_service.py reference
- Update test metrics: 880+ unit tests (was 940+/960+)
- Update coverage: 88%+ (was 87%)
- Fix testing.md exception example: SessionNotFoundError (was ToolError)

Cleanup:
- Remove test_output/ directory artifacts
- Remove one-time automation scripts (3 files)
- Auto-format 8 files with ruff (from recent refactoring)

All quality checks passing:
- Ruff linting: ✓
- Ruff formatting: ✓
- MyPy type checking: ✓
- Tests: 872 passed, 10 skipped
