Migrate peerDependencies and imports from @mariozechner/* to @earendil-works/*

[stcl-bsm]

What

Migrates peerDependencies and source imports from the deprecated @mariozechner/* scope to the current @earendil-works/* scope.

Why

• @mariozechner/pi-coding-agent carries three open security advisories (GHSA-jfgx-wxx8-mp94, GHSA-r95r-rj6r-c39x, GHSA-7v5m-pr3q-6453) and trips npm audit for every consumer.
• pi's extension loader already aliases @mariozechner/* to its bundled @earendil-works/* packages at runtime, so the deprecated packages are pulled only to satisfy the peerDependencies and are never executed.

Changes

• package.json: rename the three @mariozechner/* peerDependencies to @earendil-works/*
• extensions/usage/core.ts: update the @mariozechner/pi-ai dynamic import
• extensions/usage/index.ts: update the @mariozechner/* imports

Closes #1

Thanks for the PR! The actual content change is correct and clean — I verified that beyond the whitespace noise, it's exactly a 6-line rename of the @mariozechner/* scope to @earendil-works/*, matching the description. However, there are a few issues to fix before merging:

1. CRLF line endings (main issue)

Every line of every file has been rewritten with CRLF endings — that's why the diff shows +1032/−1032 instead of +6/−6. This looks unintentional (likely a Windows editor or core.autocrlf setting). Please restore LF endings, e.g.:

# after adding a .gitattributes with: * text=auto eol=lf
git add --renormalize .
git commit -m "normalize line endings"

2. Needs rebase — conflicts with master

master has moved ahead (7b8ddea: Kimi support, Codex auth fix), and merging currently conflicts in all three files (core.ts, index.ts, package.json) — mostly due to the CRLF rewrite making every line look changed. Please rebase onto the latest master.

3. package-lock.json is stale

The repo commits a lockfile, and its root-package peerDependencies section still records @mariozechner/*. Please regenerate after the rename:

npm install --package-lock-only

Once the CRLF noise is gone, the diff should shrink to ~6 lines and this should be good to merge. Thanks!
