Ports the app launcher implementation into the bootstrapped package. Builds on the bootstrap in #681.

What lands.

• The seven blocks: AppLauncher (docked popover shell), AppLauncherTrigger (the waffle button), AppLauncherSearch (SearchBox with the Escape chain), AppLauncherSection, AppLauncherGrid, AppLauncherList, AppLauncherItem (tile or row).
• Default and full docking, the trigger slot (toolbar/drawer placement), the pinned search, and the disabledFocusable item option.
• The package README (install, quick start, blocks and props, composition patterns, behavior notes, "Texts and localization").

Storybook mapping. Twelve stories trace the documented behaviors:

Story	What it shows
Kitchen sink	Search + recent rows + pinned tiles + all-apps grid
Docked to the app bar	Default docking under a top bar
Full dock	Full-height docking with 40 tiles scrolling internally
Trigger-anchored list	A list floating below its trigger, end-aligned
Toolbar trigger	The waffle as one command of a drawer toolbar
Disabled items	disabled beside disabledFocusable — same muted look, different reachability
Icon treatments	Monochrome Fluent icons, colorful logos, long labels
Search states	Filtering, empty state, the clear button, the Escape chain (tiles)
Controlled open	Close-on-activate and the recent list updating on reopen
Item actions	Activating a tile or row fires the item's onClick, shown in a live activation log
Localization	Every string passed as a prop — German chrome, and Armenian chrome with localized app names
Branded bars	The launcher on application bars in several brand colors

Test port. The 37 tests run under the repository's Jest runner and Testing Library. The port was mechanical: render/fireEvent/screen and Jest's own spies. The assertions are DOM-level (attributes, focus, event effects), not framework-specific; visual states are not unit-tested (no layout engine) and are covered by the stories.

Design decisions. The rationale behind the token choices, the enabled-skin guards, the two disabled flavors, the Escape chain, the pinned search (including the surface-padding compensation), the docking radii, the trigger slot and the text model is documented per decision in the dossier; summarize the relevant part here when reviewers ask.
