docs: consolidate documentation structure

Simplifies documentation by removing redundant multi-project setup guide
and consolidating into:
- README.md - User-facing installation and usage
- CONTRIBUTING.md - Developer guide for local development

Changes:
- Removed SETUP-FOR-OTHER-PROJECTS.md (redundant)
- Created CONTRIBUTING.md with development workflow
- Simplified README "How It Works" section
- Added proper Development and License sections to README
- Improved contact information with issue tracker link

The bridge works as a standard MCP server - no special multi-project
setup needed. Just configure MCP and use the tools.
