+- Removed unused `case 'agents'` from `getCategoryIcon()` in `templates.js`
+

+
+## Summary
+Merged the 15 agent templates into the existing AI category so they appear under the AI tab in the template picker, instead of a separate Agents tab that wasn't rendering.
+
+---
+
+## 1. Category Change
+**Files:** `js/templates/agents.js`
+**What:** Changed `category: 'agents'` to `category: 'ai'` on all 15 template objects.
+**Impact:** All agent templates now show under the AI tab in the template picker modal.
+
+## 2. Dead Code Cleanup
+**Files:** `js/templates.js`
+**What:** Removed `case 'agents': return 'technical'` from `getCategoryIconClass()` and `case 'agents': return 'bi-person-gear'` from `getCategoryIcon()`.
+**Impact:** No unused switch cases; cleaner code.
