test: remove stale Key rules assertions from docs test

## Why
The ## Key rules section was intentionally removed from AGENTS.md as
redundant. Two test assertions — one requiring its presence in AGENTS.md
and one confirming it was absent from CLAUDE.md — are now stale and block
pushes.

 ## Working context
 
 This repo is built by a junior developer as a homelab tool intended to scale to professional environments. Challenge ideas and reference industry standards rather than validate assumptions. Explain the why behind decisions — assume the user is learning, not just executing. Flag significant actions before taking them.
