Gave the docs steroids. sorry for the big pr. (#4892)

* Scaffold Astro + Starlight docs site

Bootstraps a new docs-astro project to replace the Hugo-based docs,
using Astro's Starlight framework with the content collection schema
and sidebar navigation configured for WinUtil's docs structure.

* Add WinUtil-branded Starlight theme

Restyles Starlight's default look with a dark-by-default grayscale
palette and WinUtil's brand blue (#0567ff, from the app logo) as the
single accent, Geist for UI text, and JetBrains Mono for code. Also
overrides the default theme provider so first-time visitors land on
dark mode instead of following OS preference.

* Add custom Hero and CornerCard components

Hero overrides Starlight's default hero with a full-bleed grid/glow
background, a browser-chrome-framed screenshot, and a badge row driven
by frontmatter data. CornerCard is a bordered feature card with corner
brackets, used for the landing page's feature grid.

* Migrate docs content from Hugo to Astro/Starlight

Ports the landing page, user guide sections, FAQ, known issues,
contributing guide, and a sample generated tweak reference page from
the Hugo site, converting Hugo shortcodes and GFM alert syntax to
their Starlight/MDX equivalents.

* Use Windows-style caption buttons in hero window chrome

Swap the macOS traffic-light dots for a minimize/maximize/close
button group, since WinUtil is a Windows tool.

* Use Windows-style caption glyph for terminal code blocks

Replace Expressive Code's default macOS dots on terminal-framed code
blocks with a right-aligned Windows minimize/maximize/close icon,
matching the hero window chrome.

* Archive the Hugo docs site as docs-old

* Promote Astro/Starlight docs from docs-astro to docs

* Show the launch command as a copyable code block on the docs homepage

* Add docs codeowner for seanh1995

* Register custom Header component for Starlight docs site

* Add custom navbar links to Astro docs, matching the old Hugo site's top nav

* Point dev docs generator at the Astro/Starlight docs site

Output moves from docs/content/dev (Hugo) to
docs/src/content/docs/code-reference (Astro/Starlight): .mdx instead
of .md, Starlight-style title="..." code fence labels instead of
Hugo's filename/linenos shortcode, and a ":::note" aside linking back
to each entry's source file. Frontmatter description is now pulled
from the JSON Description field. Also fixes a pre-existing bug where
the embedded JSON snippets were always missing their own closing
brace.

* Add seanh1995 as codeowner for the dev docs generator

* Wire up Code Reference section in docs sidebar

Adds an Architecture & Design page plus autogenerated Tweaks/Features
Reference groups pointing at docs/src/content/docs/code-reference, and
fixes the editLink base URL to the promoted docs/ path.

* Port architecture doc to code-reference and drop stale hyperv sample

Moves the Hugo-era architecture doc into
docs/src/content/docs/code-reference/architecture.mdx: drops the
Hugo-only weight/toc frontmatter, converts the embedded code fences to
Starlight's title="..." syntax, and repoints the "Related
Documentation" links at this site's actual slugs. Also removes the
hand-written reference/tweaks/hyperv.mdx placeholder now that the
generator produces the real page under code-reference/features.

* Keep pre-conversion backup of devdocs-generator.ps1

Snapshot of the script before it was pointed at the Astro/Starlight
docs site, for reference.

* updated workflow

* Update CODEOWNERS

* Hide edit-page link on the docs landing page

The splash-template landing page isn't a source doc meant to be edited
via GitHub like the rest of the guides, so skip showing the link.

* Add site footer with copyright line, matching the old Hugo docs

The Hugo site rendered "© {year} Chris Titus Tech. All rights
reserved." in its footer; Starlight's default footer had no
equivalent. Override it to append the same copyright line below the
existing edit-link/pagination row, and collapse that row entirely
when it has nothing in it (e.g. pages with editUrl disabled and no
prev/next) instead of leaving an empty gap.

* Fix vertical alignment and size of the arrow icon in hero/CTA buttons

The right-arrow icon read as floating above the button label's
baseline. Root cause was partly a genuine optical mismatch (fixed with
a small position nudge scoped to just the arrow icon, so it doesn't
also shift the unaffected GitHub icon) and partly the final CTA's copy
getting wrapped in a <p> by MDX's markdown parser, which behaved
slightly differently under the flex layout than the Hero component's
plain text node. Switching the CTA button's label to a JS string
expression avoids the wrapper and keeps both buttons' markup, and
rendering, identical.

* Use the dark fork-button screenshot in the contributing guide

Drop the unused light-mode variant and point the guide at
Fork-Button-Dark.png instead.

* Remove old Hugo docs site and pre-conversion backup files

The docs have moved to the Astro/Starlight site; the Hugo site
(docs-old/), its workflow backup, and the devdocs-generator.ps1
pre-conversion snapshot are no longer needed.

* keeping ai happy

* Bump sharp to 0.35.3 in docs site
