chore: Add GitHub Projects MCP server for AI agent board access

Adds a project-scoped MCP configuration pointing at the official GitHub
MCP server's projects toolset. This gives AI agents (Claude Code cloud
sessions, local agents) CRUD access to the psake org project board,
which is otherwise unreachable from cloud sandboxes because their
GitHub API proxy only serves a pinned set of GraphQL operations and
Projects v2 has no REST API.

The server authenticates with a GH_TOKEN environment variable (classic
PAT with the project scope, or a fine-grained PAT with Projects
permissions). Agents without GH_TOKEN set simply see the server as
unavailable; nothing else changes.
