Widening pass on top of the #38820 salvage: a full-graph audit of every
SKILL.md (bundled + optional) found 13 more references to skills that
no longer exist. Classes:
- deleted in the 38d3c49aaf bundled-skill cleanup: generative-widgets,
spotify, cloudflared-quick-tunnel, webhook-subscriptions,
debugging-hermes-tui-commands -> dropped
- native-mcp absorbed into the hermes-agent hub skill -> re-pointed
- toolset names that were never skills: browser, image_gen -> dropped
Audit now reports zero broken related_skills references.
