Build SearchWithIntent (Cmd+K with semantic matching) #1083
Description
Context
Phase 2 of docs overhaul. Users search "how do I add rate limiting" — current search only matches keywords.
Requirements
- Cmd+K search overlay that searches skill descriptions and tags, not just page titles
- Uses Fuse.js for fuzzy matching on skill descriptions, tags, and agent keywords
- Results grouped by type: Skills, Agents, Cookbook recipes
Acceptance Criteria
- Fuse.js index built from skill/agent metadata at build time
- Cmd+K overlay component with grouped results
- Search covers: skill names, descriptions, tags, agent descriptions
- Sub-200ms response time for all queries
