* fix: use baseUrl in meta tag paths for correct deployment URLs

* feat(docs): complete Phase 2 - split files and fix broken links

* fix(build): use file glob instead of sidebar parsing for llms-full.txt

Replace brittle sidebar.js regex parsing with recursive file glob.
The old approach captured non-file strings like 'autogenerated' and
category labels, resulting in only 5 files being processed.

Now correctly processes all 86+ markdown files (~95k tokens).

* fix(seo): use absolute URLs in AI meta tags for agent discoverability

AI web-browsing agents couldn't follow relative paths in meta tags due to
URL security restrictions. Changed llms-full.txt and llms.txt meta tag
URLs from relative (baseUrl) to absolute (urlParts.origin + baseUrl).

* refactor(docs): recategorize misplaced files per Diataxis analysis

Phase 2.5 categorization fixes based on post-migration analysis:

Moved to correct Diataxis categories:
- tutorials/installation.md → deleted (duplicate of how-to/install-bmad.md)
- tutorials/brownfield-onboarding.md → how-to/brownfield/index.md
- reference/faq/* (8 files) → explanation/faq/
- reference/agents/barry-quick-flow.md → explanation/agents/
- reference/agents/bmgd-agents.md → explanation/game-dev/agents.md

Created:
- explanation/agents/index.md

Fixed all broken internal links (14 total)

* feat(docs): add Getting Started tutorial and simplify build script

- Add comprehensive Getting Started tutorial with installation as Step 1

* fix(css): use fixed width layout to prevent content shifting

Apply React Native docs approach: set both width and max-width at
largest breakpoint (1400px) so content area maintains consistent
size regardless of content length. Switches to fluid 100% below
1416px breakpoint.

* refactor(docs): migrate from Docusaurus to Astro+Starlight

Replace Docusaurus with Astro and the Starlight documentation theme
for improved performance, better customization, and modern tooling.

Build pipeline changes:
- New build-docs.js orchestrates link checking, artifact generation,
  and Astro build in sequence
- Add check-doc-links.js for validating internal links and anchors
- Generate llms.txt and llms-full.txt for LLM-friendly documentation
- Create downloadable source bundles (bmad-sources.zip, bmad-prompts.zip)
- Suppress MODULE_TYPELESS_PACKAGE_JSON warning in Astro build
- Output directly to build/site for cleaner deployment

Website architecture:
- Add rehype-markdown-links.js plugin to transform .md links to routes
- Add site-url.js helper for GitHub Pages URL resolution with strict
  validation (throws on invalid GITHUB_REPOSITORY format)
- Custom Astro components: Banner, Header, MobileMenuFooter
- Symlink docs/ into website/src/content/docs for Starlight

Documentation cleanup:
- Remove Docusaurus _category_.json files (Starlight uses frontmatter)
- Convert all docs to use YAML frontmatter with title field
- Move downloads.md from website/src/pages to docs/
- Consolidate style guide and workflow diagram docs
- Add 404.md and tutorials/index.md
