refactor: complete action testing system overhaul

- Removed /scratch directory, now cloning pullfrogai/scratch as needed
- Implemented new play.ts testing system with local and Docker/act modes
- Added environment variable propagation to cloned test repositories
- Created minimal .act-dist approach to avoid pnpm symlink issues with Docker
- Migrated from dist/index.js to entry.cjs bundled output
- Added TypeScript fixture support with MainParams type safety
- Organized all test fixtures in fixtures/ directory
- Updated publish workflow to trigger on package.json changes
- Removed unnecessary INPUT_ANTHROPIC_API_KEY references
- Added comprehensive documentation for new testing system
- Fixed pre-commit hook to use entry.cjs instead of dist/

action.yml
