476c1baf40 Add GitHub MCP proxy with repo scope enforcement
- Host-side proxy that injects GitHub tokens and enforces single-repo scope
- Defense-in-depth: owner/repo checks, search query scoping, tool allowlist,
  server-side X-MCP-Toolsets/Lockdown headers, header protection
- Token generation via GitHub App device flow with repo-scoped OAuth tokens
- Comprehensive tests (unit + end-to-end with mock upstream server)
