chore: bump version to 2.7.2 and update HTTP deployment documentation

- Added warning about experimental remote server deployment
- Clarified HTTP bridge architecture in documentation
- Added deployment scenarios section explaining local vs remote options
- Enhanced troubleshooting with bridge-specific issues
- Created http-bridge.js for local HTTP testing
- Fixed HTTP server to include management tools in tools/list

The documentation now clearly explains:
- Why "node" command is used instead of "docker" (stdio bridge requirement)
- Three deployment scenarios with pros/cons
- How to test locally with Docker
- Bridge architecture (Claude Desktop → bridge → HTTP server)
