GNAP MCP server: expose git-native agent coordination board as an MCP resource

Proposal: GNAP MCP server for agent-to-agent task coordination

The MCP servers repository already has a Git reference server for reading/searching/manipulating git repositories. There's a natural extension: a GNAP server that exposes a git-native agent coordination board as MCP resources and tools.

GNAP (Git-Native Agent Protocol) coordinates multiple AI agents via a shared git repo: tasks in board/todo/ → board/doing/ → board/done/. It's agent-to-agent coordination, complementary to MCP's agent-to-tool focus.

Proposed GNAP MCP server:

// Resources
'gnap://board/todo'   // List available tasks
'gnap://board/doing'  // List in-progress tasks  
'gnap://board/done'   // List completed tasks

// Tools
'gnap_claim_task'     // Claim a task (todo → doing)
'gnap_complete_task'  // Complete a task (doing → done, with result)
'gnap_create_task'    // Create a new task in board/todo/
'gnap_read_task'      // Read task content (spec or result)

This builds directly on the existing Git MCP server — GNAP uses git operations that the Git server already provides. The GNAP server would add coordination semantics on top.

Why this belongs in reference servers:

MCP defines how agents access tools. GNAP defines how agents coordinate with each other. Together, they form a complete agent interoperability stack. A GNAP MCP reference server would:

1. Demonstrate multi-agent coordination patterns in MCP
2. Provide a reusable coordination server for the community
3. Complement the existing Git server with agent coordination semantics
