The skills are functionally complete and standalone — superpowers
references were attribution-only. Removed so a reader without the
superpowers plugin loaded isn't sent chasing dead links.
Plus: .claude/skills/<name> symlinks so Claude Code's Skill tool can
invoke them by name (analogous to the existing .claude/agents/
symlinks). Discovery section in skills/README.md updated to cover
both symlink sets.
Three symlinks per skill:
.claude/agents/implement -> skills/implement/agents
.claude/agents/audit -> skills/audit/agents
.claude/agents/debug -> skills/debug/agents
Tracked so contributors get correct subagent dispatch on clone.
Resolved correctly via 'ls -L'.
