Subject: [PATCH] docs(site): inject LLM-nav banner + 'See also' footer into
 every .md
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirrors the code.claude.com/docs pattern so any .md fetched by an LLM
points back to the site index and surfaces 3-5 related pages.

Every per-page .md emitted by starlight-page-actions now starts with
a blockquote banner linking /llms.txt and the three scoped bundles
(user-guide, mcp, contributing), and ends with a hand-curated
"See also" section.

The curation lives in packages/docs/scripts/inject-llm-nav.mjs as a
RELATED map keyed by page slug — one entry per page. The script runs
as an astro-build postbuild step (build = "astro build && node
scripts/inject-llm-nav.mjs") and is idempotent.
