chore: reconcile publish/agent surfaces after PR batch

- agent.yaml: register epic-* commands (#2236) and vue-review (#2241)
- package.json files: drop stray skills/ml-adoption-playbook entry (follows orphan-skill publish pattern; not in install-modules.json)
- unicode-safety: strip decorative emoji from dashboard-web.js (#2100) and brand-discovery refs (#2221) to pass the CI gate
- agent-compress: raise catalog token canary 5000 -> 6000 for the 67-agent catalog

Full suite green (2836/2836).
