fix-agent-qa-ticket

Fix an Architect QA triage ticket (agtqa_*) end-to-end via the raw agents API: fetch the ticket + conversation, find the root-cause procedure or prompt text, fix it on a branch, add + run a simulation test proving the fix, then post a summary comment on the ticket. Use when asked to "fix agtqa_...", "address this QA ticket", "triage and fix this Architect ticket", or given an agtqa_* id/URL.
