Add build_manual.build_site(), which walks docs/manual and emits the
Astro Starlight content collection: plain pages copied with pipeline-only
frontmatter (man/site/manTitle/helpKeywords) stripped, and *-functions/
category files exploded into one page per function plus a CardGrid/LinkCard
overview. Writes src/sidebar.json for astro.config.mjs to import. Wires
--site alongside the existing --concat flag.
Fixes two latent defects found while building the real site against the
strict content.config.ts schema:
- _split_entries now tracks fenced code blocks (like
manualtools.shift_headings does) so a `## ` inside a fence can't be
mistaken for an entry boundary.
- LinkCard title/description are escaped for JSX attribute context, since
shell synopses routinely contain `<placeholder>` angle brackets that
would otherwise open unterminated MDX/JSX parsing.
Also fixes the generated sidebar shape for the functions category: Starlight
0.39+ dropped support for a bare `autogenerate` sibling of `label` on a
top-level group, so the autogenerate config now nests inside `items`.
Verified with a full `astro build` (temporarily pointing astro.config.mjs
at the generated sidebar.json, then reverted since replacing that config
is a later task's deliverable): 120 pages built cleanly, no
content-collection/frontmatter/MDX errors.
