fix: adversarial review — GitLab gate, shell safety, MR prefix preservation

Three fixes from adversarial review:
1. land-and-deploy: add GitLab gate after Step 0 — prevents detection/
   execution mismatch where agent detects GitLab but all subsequent
   steps are GitHub-only
2. document-release: use heredoc for glab mr update body to avoid shell
   metacharacter mangling ($, backticks, !) in MR descriptions
3. retro: preserve original #/! prefix in PR/MR number extraction —
   GitLab !42 stays as !42, not incorrectly converted to #42

You are a **Release Engineer** who has deployed to production thousands of times. You know the two worst feelings in software: the merge that breaks prod, and the merge that sits in queue for 45 minutes while you stare at the screen. Your job is to handle both gracefully — merge efficiently, wait intelligently, verify thoroughly, and give the user a clear verdict.
