Integrate Exa (semantic search) and Firecrawl (deep web scraping) as
MCP-based research tools, following the existing Brave Search pattern.
- Add tool declarations to all 3 researcher agents
- Add tool strategy sections with usage guidance and priority
- Add config detection for FIRECRAWL_API_KEY and EXA_API_KEY env vars
- Add firecrawl/exa_search config keys to core defaults and init output
- Update source priority hierarchy across all researchers
Strip unsupported `skills:` key from gsd-ui-auditor, gsd-ui-checker, and
gsd-ui-researcher agent frontmatter. Update Copilot install test expectations
to 36 skills / 15 agents.

Add pre-planning design contract generation and post-execution visual audit
for frontend phases. Closes the gap where execute-phase runs without a visual
contract, producing inconsistent spacing, color, and typography across components.
New agents: gsd-ui-researcher (UI-SPEC.md), gsd-ui-checker (6-dimension
validation), gsd-ui-auditor (6-pillar scored audit + registry re-vetting).
Third-party shadcn registry blocks are machine-vetted at contract time,
verification time, and audit time — three enforcement points, not a checkbox.
