Introduce MetadataContext + useMetadata hook backed by localStorage and
wire a Braces button into the sidebar footer that toggles raw metadata
visibility across the app. Replace per-page collapsible metadata in
PeerDetail and WorkspaceDetail with a global animated reveal styled
distinctly (warning-colored card) to signal raw payload. Also adopts
the shared Breadcrumb in both detail pages.
Add /explore redirect route that maps Honcho's deep-link shape
(?workspace=...&view=...&session=...) onto our existing flat routes,
so any app.honcho.dev URL works against a self-hosted instance by
swapping the host.
Wire tauri-plugin-deep-link to register the openconcho:// scheme on
desktop and forward incoming URLs into the router on launch and at
runtime.
Bug 1: On a fresh load with no saved config, RootLayout returned `null`
while a useEffect-driven `router.navigate()` fired, leaving a blank screen
until the user manually refreshed. Move the redirect into the root route's
`beforeLoad` so it happens synchronously during route resolution and the
settings form renders on first paint.
Bug 2: `DemoProvider` was mounted inside `RootLayout` only on the
non-settings branch, so any component reading `useDemo()` outside that
branch would throw "useDemoContext must be used within DemoProvider".
Hoist `<DemoProvider>` to `main.tsx` so the context is available app-wide.
Adds vitest + RTL setup with regression tests for both behaviours.
