changes

Manages `~/.pi/agent` config via the itme-brain/pi submodule and
provides nodejs_20 with NPM_CONFIG_PREFIX=~/.npm-global so pi and its
extensions install via the global npm ecosystem.

Pi itself and extensions like pi-mcp-adapter are installed manually
via `npm install -g` rather than packaged through nix — the ecosystem
moves too fast to keep derivations current.
