fix: plugin.json missing 3 skill registrations #1
Description
Problem
The plugin.json only registers agent-builder, but the repository contains 4 skills:
- agent-builder ✓
- media-writer ✗
- skill-judge ✗
- vibe-coding ✗
Solution
Register all 4 skills in the plugin manifest so they are discoverable by Claude Code.
Impact
Without this fix, 3 out of 4 skills are never loaded, making them effectively invisible to agents.
