Add repo-standardizer skill: polish any GitHub repo surface

[programmingWTF]

Summary

Adds repo-standardizer — a skill that polishes any GitHub repository's surface: label taxonomy (emoji rating tiers, P0–P3 priority, impact severity), issue forms, PR template, CI workflows (Node/Python/Go/Rust), CODEOWNERS, rulesets, and docs. Repo metadata & config only — never touches code logic.

Why it fits

• Complements the existing ai-ready skill (which generates AI config files): repo-standardizer handles the repo surface — labels, issue forms, PR template, CI config, branch rulesets, docs
• Agent-agnostic and idempotent: safe to re-run, never clobbers user content, auth-first dry-run
• Published on ClawHub (@programmingwtf/repo-standardizer, v1.0.0, clean security scan) with a v1.0.0 release

Details

• — SKILL.md + 22 templates (labels.json, issue forms, CI workflows, CODEOWNERS, docs)
• — regenerated via npm run build
• npm run skill:validate passes (411/411 skills valid)
