chore: remove legacy maintainer loop

[BramVR]

Brings origin/main in line with the local main checkout, which has been carrying this change unpushed.

Why

b54218a1 "chore: remove legacy maintainer loop" was committed locally but never reached origin/main. Because PRs #6 and #7 were squash-merged, git sees no shared history between the local commits and their squashed counterparts, so a plain git pull cannot reconcile the two sides. Cherry-picking the one commit that is genuinely missing is the clean way to close the gap.

After this lands, origin/main holds everything, and the local checkout can simply reset onto it.

What changed

Removes the legacy current-repository bram-maintainer-loop skill (412 lines) and its prompts/bram-maintainer-project-loop.md, then repoints every $bram-maintainer-loop reference at $bram-maintainer-loop-v2 across AGENTS.MD, README.md, VISION.md, config/bram-loop-repos.txt, and the github-project-triage, tdd, to-issues, to-prd skills. Maintainer orchestration now routes only through v2.

Conflict resolutions

The cherry-pick hit four conflicts, all caused by PRs #6 and #7 having reshaped the same regions:

• README.md — the original commit edited the hand-maintained Codex symlink list that feat: add sync-skills skill mirror #6 deleted in favour of the scripts/sync-skills section. Kept the sync-skills version; the edited line is obsolete because the mirror is generated.
• skills/codex-first/SKILL.md — both sides rewrote the maintainer pointer line. Kept feat: adopt codex-huge-context, refresh codex-first #7's wording ("Whole-repo/multi-repo maintainer coordination"), which already said $bram-maintainer-loop-v2.
• AGENTS.MD — kept feat: add sync-skills skill mirror #6's scripts/sync-skills rule and took this commit's -v2 rename in the upstream-sync preserve list.
• CHANGELOG.md — kept all four entries, newest first.

Verification

scripts/validate-skills passes at 41 skills, down from 42 exactly as expected with bram-maintainer-loop gone. No non-historical $bram-maintainer-loop references survive — the only remaining mentions are past changelog entries, which correctly describe what happened at the time.
