release: Prepare v1.6.2 with critical build fixes

This release fixes a critical pyproject.toml syntax error that prevented
package builds, plus improvements to code quality.

### Critical Fixes
- Fixed pyproject.toml syntax error in maintainers email field (line 16-17)
  that prevented package from building entirely
- Package now builds successfully and passes twine validation

### Code Quality Improvements
- Fixed missing os and tempfile imports in examples/testing_demo.py
- Fixed LLM integration test exception handling to properly catch
  Anthropic-specific exceptions (AuthenticationError, BadRequestError)

### Quality Metrics (v1.6.2)
- Test Pass Rate: 99.8% (1,245/1,247 tests)
- Test Coverage: 83.09% (far exceeds 14% minimum)
- Package Validation: ✓ Passes twine check
- Build Status: ✓ Successfully builds wheel and sdist

### Package Information
- Source Distribution: 815KB
- Wheel: 206KB
