implement-full-spec

Use when the operator points at a parent ticket, audit, RFC, design doc, or multi-finding report with N actionable subtasks and wants every subtask shipped as its own stacked pull request, then driven to merge-ready by addressing every bot/human review comment and re-requesting review per round. Triggers on: 'fix all subtasks of [ticket]', 'work through P1/P2/P3 items', 'open a PR per finding and stack them', 'ship the audit remediations', 'knock out this report end to end', 'use agent teams to fix [parent]', 'address all comments on these stacked PRs', 'drive the stack to merge-ready', 'do a review-response sweep', 'comment @bot re-review when done'.
