Cut duplicated and speculative code across the package

An over-engineering audit of the whole tree, applied in five reviewed
batches. Behaviour stays the same except where UPGRADE.md says otherwise.

PHP: the showcase and error-page stylesheets are prebuilt into
resources/dist by bin/stylesheets.mjs, through Vite's own postcss-import
(first occurrence kept, the order an application's build gives), instead
of Stylesheets::bundle() inlining imports on every request; only the
import walk DesignGuard needs stays. SchemeStylesheet::withProfiles()
replaces three copies of the scheme-plus-profiles loop, material:scheme
leaves spec and contrast checks to the node script that already made
them, and the error page's scheme cache, the hashed view namespace, the
translations path with no lang/ folder and DesignGuard's 1.x-name hints
are gone.

JS: the androidx shape port progress.js and both bin scripts each carried
lives once in resources/js/shapes.js (the generated SVGs are unchanged);
util.js holds ringIndex(), ms(), reopenGuard() and remember(), which
were written out several times; listeners are released through
AbortController; tooltip.js's hoverPopover() serves the rich tooltip too.

CSS: every rule for an element inside the navigation rail queries
`--md-navigation-rail-value` instead of repeating the seven collapsed
conditions under five media branches; badge, alert, progress, slider and
button read one non-inheriting colour-role table (components/color.css);
the dialog chrome, the submenu's popover chrome, the chip's state layer
and touch target, and the visually-hidden inputs use the shared rules
they copied; foundation/tokens.css is folded into foundation.css.

Views: Support\Field and Support\Link replace the error-key, bound-value
and link-attribute blocks copied into the fields and link components;
the timepicker period group, the menu filter and the showcase head are
partials; the datepicker's steppers and entry fields are loops; component
docblocks no longer restate SKILL.md.

Tests and tooling: one dataset-driven ComponentStylesheetsTest replaces
four per-group files, DesignGuardTest and the layout-component tests use
datasets, browser tests share one ready() helper, CSS parsing lives in
ComponentStylesheet alone. docs/audits and the finding IDs citing it are
removed, as are pestphp/pest-plugin-laravel, the unused composer scripts
and check:font; the lint job runs in the feature job, which now installs
node packages so the prebuilt-stylesheet staleness test runs in CI.

Feature suite 1177 passed, Chrome browser suite 299 passed.

-The guard reads every path it is given and fails, with `path:line` and the 2.0.0 replacement, on any Tailwind utility or variant still in a view, PHP or JS file, a colour of the application's own Tailwind theme (`bg-brand`) included — none compiles, since the application carries no Tailwind — and on 1.x's own utilities (`type-body-md`, `text-meta`, `rounded-corner-lg`, `focus-ring`): a layout component and prop (`flex gap-4` → `<x-row gap="space200">`), an `md-*` class (`truncate` → `md-truncate`), or a token for the application's own CSS (`rounded-lg` → `var(--md-sys-shape-corner-lg)`). A class the application's own stylesheets declare is exempt. In the `.css` files it is given (`material-scheme.css` skipped) it fails on a literal colour, radius, shadow, font, easing or duration, and on a media query off M3's 600/840/1200/1600px; a `var()`, or a `calc()`/`min()`/`max()`/`clamp()` built on one, is fine. It also fails on unknown Material Symbol names and Blade directives written inside component tags. Markdown mail components (under `mail.markdown.paths`, `resources/views/vendor/mail` by default) are the mail theme's to style: their classes are not read as Tailwind, and a mail theme stylesheet there is neither checked for literals nor a source of exempt classes.

 `missingStylesheets($cssEntry)` checks the entry's relative `@import` graph, followed through every package file's own imports, against the package tags the views render (unprefixed, under the configured prefix, or `<x-livewire-material::…>`), `->links()` and the rows they write by hand (`data-md-list-row` on anything but `<x-card>` needs `components/list-item.css`), and names each missing `@import` line once; a tag the application shadows with its own component is reported instead. It reads imports only, so leave `resource_path('css')` out of `scan()` while the stylesheets still hold literals. `forbidColours([...])` names roles the application leaves out, and fails wherever one (with its `on-` and container roles) is still written: `var(--md-sys-color-…)` in CSS or an inline `style`, its `md-ink-*` class, or a component's `color`/`tone` prop. `forbid($pattern, $reason)` adds any pattern of your own, line by line.
