Rename to @earendil-works/pi-coding-agent + earendil-works/pi URL

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).

Sweep:
- extensions/pi/mempalace.ts: 'import type { ExtensionAPI } from
  "@mariozechner/pi-coding-agent"' -> @earendil-works/pi-coding-agent.
- README and extensions/pi/README: github.com/mariozechner/pi-coding-agent
  URL refs -> github.com/earendil-works/pi.
- install.sh: same URL substitution in the user-facing pointer line.

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

 ### Deploying pi on a new machine (full recipe)
 
-If the target machine also runs [pi](https://github.com/mariozechner/pi-coding-agent), the recipe is: install [`pi-toolkit`](https://gitea.jordbo.se/joakimp/pi-toolkit) first (pi's own base config), then this toolkit (adds the pi↔mempalace MCP bridge). Full step-by-step: **[`extensions/pi/README.md` § Deploying pi with mempalace on a new machine](extensions/pi/README.md#deploying-pi-with-mempalace-on-a-new-machine)**.
