Description: Implements a single GitHub Issue end-to-end inside an isolated git worktree and opens a pull request. Use when asked to pick up an issue, implement a fix or feature, deliver a PR, or "make a PR for #N". Requires the agent:ready label. NOT for multi-issue coordination without conflict analysis (use issue-raid-commander first). NOT for discovering issues (use issue-ranger) or running a full sprint (use dispatching-guild-expedition). Does NOT merge PRs.
