Hotfix: cap the MCP SDK dependency at mcp<2.
mcp 2.0.0 (2026-07-28) removed mcp.server.fastmcp and renamed the server class to MCPServer. Because the dependency was unbounded (mcp>=1.2.0), uvx spudcoach re-resolved to 2.0.0 and crashed on import with ModuleNotFoundError: No module named 'mcp.server.fastmcp'.
This release pins mcp>=1.2.0,<2 (resolves to 1.29.0, which still ships fastmcp), restoring uvx spudcoach launches. The port to the mcp 2.0 MCPServer API is tracked in the roadmap.
