feat(lanes): surface child worktrees on a lane card + detect Superpowers skills

Adopting the main repo as its own lane now gets stage detection
(cwd matches, same as any other lane), and its card lists every
managed-worktree lane provisioned from it with a jump-to link.
Also add the two missing Skill-tool detect rules (implement, ship)
so detection covers all four Superpowers workflow phases, not just
plan/review.
