Rename github URL refs to earendil-works/pi

Pi moved to its new home at earendil-works on 2026-05-07
(https://pi.dev/news/2026/5/7/pi-has-a-new-home).

URL substitution:
  https://github.com/mariozechner/pi-coding-agent
  -> https://github.com/earendil-works/pi

(coding-agent now lives at packages/coding-agent inside the new
monorepo root, but linking to the root is the canonical reference
per the announcement post).

Brew install references (`brew install pi-coding-agent`) left as-is:
the homebrew formula still works at 0.73.1 and a tap update is
tracked upstream at earendil-works/pi#2755.
