fix: ensure MCP and skills config changes are immediately reflected

Browse Source 
- Use ExtensionsConfig.from_file() instead of cached config to always
  read latest configuration from disk in LangGraph Server
- Add mtime-based cache invalidation for MCP tools to detect config
  file changes made through Gateway API
- Call reload_extensions_config() in Gateway API after updates to
  refresh the global cache
- Remove unnecessary MCP initialization from Gateway startup since
  MCP tools are only used by LangGraph Server
