- Normalize GET /api/skills/:id/content handling by decoding encoded IDs and returning consistent invalid-id and not-found responses
- Update readSkillContent to use stat-based file vs directory detection, read SKILL.md robustly, and list non-SKILL.md entries
- Refine SkillsView interactions to ignore toggle clicks, support explicit retry of failed content fetches, and show a SKILL.md fallback placeholder
- Add/adjust dashboard route, component, and mobile CSS tests to cover content route behavior, retry flow, and touch-friendly detail panel styles
