All-in-MCP FastMCP Proxy Server

and other MCP servers with advanced features like LLM sampling forwarding,
progress reporting, and logging.
Environment variables to enable MCP servers (all disabled by default):
- ENABLE_APAPER=true: Enable APaper academic search server
- ENABLE_GITHUB_REPO_MCP=true: Enable GitHub repository MCP server
- ENABLE_QWEN_SEARCH=true: Enable Qwen/Dashscope web search server
