fix(release-promote): grade svn mv -m, not a separate svn commit

[Shaurya2k06]

Summary

• Fix the release-promote step-2 eval grading rule so svnpubsub requires
  svn mv with inline -m referencing the [RESULT] [VOTE] URL, not a
  separate svn commit -m that the skill never emits and SVN does not need
  for URL-to-URL moves.
• Retarget two release-promote SKILL.md lines from "svn commit message" to
  "svn mv -m message" so the prose matches the paste-ready command block.

Type of change

• Skill change (.claude/skills/<name>/) — eval fixtures updated below
• Other: uv.lock metadata refresh from the vendor-neutrality hook when
  the skill file was staged (mypy specifier sync)

Test plan

• PYTHONPATH=tools/skill-evals/src python3 -m skill_evals.runner tools/skill-evals/evals/release-promote/ loads all 8 cases; step-2 system prompt shows the corrected svnpubsub grading rule
• Case-1 (svnpubsub) assertion checks pass against skill-shaped output (svn mv + -m with RESULT URL; no separate svn commit)
• prek commit hooks pass on changed files
• Commit is GPG-signed and DCO-signed (Signed-off-by)

RFC-AI-0004 compliance

• HITL — any new mutation is gated on explicit user confirmation
• Sandbox — no new unrestricted host access; network reach declared in the adapter
• Vendor neutrality — placeholders used in all skill / tool prose
• Conversational + correctable — agentic-override path documented if behaviour is adopter-tunable
• Write-access discipline — no autonomous outbound messages; drafts only, sent on confirmation
• Privacy LLM — private content does not reach a non-approved LLM; redactor invoked where needed

Diagnosis confirmed against the skill itself. Its svnpubsub block emits svn mv ... -m "Promoting Apache (from rc). [RESULT]: <result_vote_url>" and there is no svn commit anywhere in it; SKILL.md line 51 and line 356 both describe the move as the promote commit. So the old rule demanded a command the skill never emits. The two SKILL.md table rows changed here were the only two svn commit mentions left in the file.
