fix(zeroclaw): remove broken zeroclaw agent (repo 404) (#3107)

* fix(zeroclaw): remove broken zeroclaw agent (repo 404)

The zeroclaw-labs/zeroclaw GitHub repository returns 404 — all installs
fail. Remove zeroclaw entirely from the matrix: agent definition,
setup code, shell scripts, e2e tests, packer config, skill files,
and documentation.

Fixes #3102
