fix(ui-design): use mcp__exa__web_search_exa for design trend research and URL analysis

- Replace mcp__exa__get_code_context_exa with mcp__exa__web_search_exa in consolidate.md
  for trend research queries (colors, typography, layout, contrast, accessibility)
- Add Phase 0.75 URL Content Analysis in imitate-auto.md for screenshot fallback mode
- Use web_search_exa for design pattern extraction from URLs when screenshots unavailable
- Update workflow documentation to reflect new MCP tool usage
