docs: add public frontmatter to docs for soulcraft.com/docs pipeline

Add YAML frontmatter (slug, public, category, template, order) to 8
existing docs and 2 new getting-started guides (installation, quick-start).
Include docs/**/*.md in npm package files so the portal sync-docs script
can read them from node_modules after publish.

Update CLAUDE.md with docs pipeline trigger phrases and release checklist.
