feat(claude,cursor): fold ponytail into deslop, wire both into code-reviewer

[stijnvanhulle]

🎯 Changes

Fold the ponytail skill and its /ponytail command into deslop, so one skill and one /deslop command run three checks in a single pass, across every tool this repo ships (Claude Code, Cursor, Codex, Gemini CLI, OpenCode). Also wire deslop, jsdoc, humanizer, and documentation into the code-reviewer subagent's review.

• /deslop runs the reuse-first decision ladder (over-engineering: unneeded deps, wrappers, config), the AI style-tell checklist (needless comments, defensive checks, any casts), and the humanizer pattern list over any changed README, doc, comment block, or markdown, so one run covers both code and prose.
• Lists every finding — file, what it violates, proposed fix — and stops before editing anything.
• Confirms with the user before applying: a native picker (AskUserQuestion) in a client that has one, a lettered list per the user-questions rule otherwise. deslop used to apply its fixes directly; it now asks first, matching how ponytail already worked.
• code-reviewer folds deslop's ladder and style tells, jsdoc's conventions, humanizer's pattern list, and documentation's style guide into its findings, in that order, then asks which to hand off for fixing. It stays read-only: it reports by these skills' criteria rather than running their apply steps.

Also updates every cross-reference (pr, humanizer skills, all six READMEs, AGENTS.md's skill list), regenerates GEMINI.md, and bumps .codex-plugin/plugin.json and gemini-extension.json (0.11.0 → 0.12.0) since the change touches .agents/skills/.

🧪 How to test

• Step 1: Run node --experimental-strip-types scripts/agentFiles.ts from the repo root.
• Step 2: Confirm it prints agent files in sync (3 command sets) with no GEMINI.md is stale warning.
• Step 3: In Claude Code, type /deslop on a branch with a diff that changes both code and a README, and confirm it lists code and prose findings and asks before editing anything.
• Step 4: Invoke code-reviewer on the same branch and confirm it reports findings by the five categories above, in order, then asks which to hand off.

✅ Checklist

• I have followed the steps in the Contributing guide.
• I ran the full pre-PR check locally: pnpm format && pnpm lint:fix && pnpm typecheck && pnpm test.

🚀 Release Impact

• This change affects published code, and I have generated a changeset.
• This change is for the docs (no release).
• This change is breaking, and the body says what breaks and what a user has to do.

Breaking change: /ponytail no longer exists. Run /deslop in its place — it now covers over-engineering, code style tells, and prose humanizing.
