Resolve GitHub Issues

Execute issue resolution workflow using isolated worktrees, TDD methodology, and agent collaboration.

Runtime notes

• Worktrees: worktrees are plain git — git worktree add -b <branch> <path> <base> to create the isolated worktree, git worktree remove <path> (plus git branch -D <branch> if needed) to clean it up. Runtimes with a dedicated worktree tool may use it instead; the result is the same.
• Skill invocation: hand PR creation to the sibling create-pr skill using the runtime's own skill-invocation mechanism — the handoff contract in references/pr-creation-handoff.md is what matters, not the call syntax.
