chore: enhance project metadata, tooling, and documentation

**Project Configuration:**
- Enhance pyproject.toml with comprehensive metadata, keywords, and classifiers
- Add LICENSE file (MIT) for proper open-source distribution
- Add PUBLISHING.md with comprehensive publishing guidelines
- Update .gitignore to exclude tool artifacts (.cache, .pytest_cache, .ruff_cache, .ty_cache)
- Ignore documentation working directories (.docs, .full-review, docs/plans, docs/sessions)

**Documentation:**
- Add extensive Unraid API research documentation
  - API source code analysis and resolver mapping
  - Competitive analysis and feature gap assessment
  - Release notes analysis (7.0.0, 7.1.0, 7.2.0)
  - Connect platform overview and remote access documentation
- Document known API patterns, limitations, and edge cases

**Testing & Code Quality:**
- Expand test coverage across all tool modules
- Add destructive action confirmation tests
- Improve test assertions and error case validation
- Refine type annotations for better static analysis

**Tool Improvements:**
- Enhance error handling consistency across all tools
- Improve type safety with explicit type annotations
- Refine GraphQL query construction patterns
- Better handling of optional parameters and edge cases

This commit prepares the project for v0.2.0 release with improved
metadata, comprehensive documentation, and enhanced code quality.
