Add dynamic example orchestration script

Replace hardcoded port assignments and npm scripts with run-all.ts that:
- Auto-discovers example directories and assigns ports
- Passes server URLs to basic-host via SERVERS env var
- Supports start, dev, and build commands

Update basic-host to fetch server list from /api/servers endpoint
and display server names from MCP server metadata.
