Plan step 17, on N-06, N-07 and C-07. The shell now changes at 600, 840 and
1200 and nowhere else: a compact window keeps the navigation bar and the modal
rail; `medium` (600-839) gets the collapsed rail in the layout and no bar;
`expanded` (840-1199) gets a standard rail, collapsed, whose menu button
expands it in place rather than over a scrim; `large` and above start it
expanded, which is what M3 prefers once there is room.
`data-rail` alone could not say "collapsed at expanded, expanded at large",
since it carries `rail.default` for a visitor who never chose. <x-theme-script>
now also writes `data-rail-auto` while nothing is stored, the `rail-collapsed:`
variant reads it in the 840-1199 band, and `$store.rail.auto` mirrors it for
Alpine; the first press of the menu button drops it, so a remembered choice
still wins in both bands. `rail.default` and the rest of `$store.rail` are
unchanged, and the attribute rides through `wire:navigate` with the others.
`--material-margin` carries M3's window margin on the shell -- 16px compact,
24px from `medium` -- and the content region is padded with it, so the showcase
pages drop their own gutters.

Package views now write <x-livewire-material::button>, so a configured
prefix (which Blade spells <x-m::button>) and an application component
of the same name can no longer break or shadow them. The showcase
rewrites its examples to the configured prefix. Adds the README, and
waits for the adaptive rail to hear a resize before the navigation
tests press its menu button.

M3 Expressive's flexible navigation bar, the collapsed, expanded and
modal navigation rail with its state applied before the first paint,
and an adaptive app shell composing them. The head script now restores
the theme and rail attributes that wire:navigate strips from <html>.
Completes Phase 8.
