fix(pi): repoint install_url to @earendil-works/pi-coding-agent (#3169) (#3214)

The @mariozechner/pi-coding-agent npm package is deprecated in favor of
@earendil-works/pi-coding-agent. Pi Coding Agent is still active under the
new org, so update the install_url rather than removing the integration.
