feat(lib): bundle MCP servers from .common/lib into factory/lib/

Copies source (no node_modules, dist, .tasks, .wiki, __pycache__) for:
- projects-meta-mcp v2.25.0 (TypeScript/Node)
- wiki-graph v0.3.1 (TypeScript/Node)
- interns-mcp v0.3.3 (Python/FastMCP)

.gitignore: exclude lib build artefacts (node_modules, dist, .venv, __pycache__, *.pyc)
bootstrap.ps1: add MCP build step — npm install+build for TS servers, venv+pip for Python
