Improves Windows installer success rate from 87% to 95% (37/39 tools).

New Features:
- Auto-install PHP runtime for phpstan (similar to Node.js)
- Auto-install Go runtime for checkmake
- Chocolatey fallback for cppcheck and cargo-clippy when winget fails

Changes:
- Added PHP and Go to tools-manifest.csv with package mappings
- Added runtime detection and auto-install prompts in cli.py
- Added choco fallback logic for specific tools
- Fixed pyproject.toml version bumper bug (ruff/mypy configs)
- Updated tool-versions.lock with new entries

Remaining Windows failures (unavoidable):
- dart: No choco package available
- swiftlint: Platform limitation (macOS/Linux only)
