feat: adopt agent-skills, scope aoe config to yolo

Drops the stale skills/commands/CLAUDE.md from home/common/programs/claude
in favour of the agent-skills flake, which is the maintained copy. The
module keeps what agent-skills does not own: packages, statusline and
settings.json.

aoe's config.toml moves to home/yolo — it sets yolo_mode_default, which
starts sessions with permission checks skipped.
