mattpocock-skills: patch
Add the implement-spec skill (in-progress bucket, user-invoked). It takes a spec and its tickets and drives them to a single PR: the tickets are read as a task graph with blocking edges, so implementer subagents run in background worktrees across the ready frontier for concurrency, a merger subagent folds each one back into the PR branch, and the flow closes with /code-review before the PR is marked ready.
