v0.7.3 -- Skills CLI, help fixes

Skills CLI Support

GSP is now listed on The Agent Skills Directory. Users can cherry-pick individual skills without installing the full pack:

npx skills add jubscodes/get-shit-pretty

This works with Claude Code, Cursor, Copilot, Gemini, and 20+ other agents. The full pack (npx get-shit-pretty) remains the recommended install for the complete pipeline with agents, hooks, and MCP servers.

Help Output Fixes

/gsp-help now lists 5 skills that were missing: brand-brief, icons, logo, scaffold, and design-system. The pipeline diagram was corrected to show the current flow (brief -> research -> strategy -> identity -> guidelines), the directory structure updated (patterns/ -> system/), and the GitHub URL fixed.

The installer post-install message now says "all skills" instead of "all commands".

Bento Grid Reference

A new bento-grid.md reference was added to gsp-project-build -- responsive layout patterns for mixed-size card grids, breakpoint strategies, and common mistakes (like using row-span at small breakpoints).
