Restore workspace after reopening app

Browse Source 
Native state restore can resume at the host route instead of the root index, so host home now resolves the remembered workspace itself. Keep shared route policy outside src/app so Expo Router does not register it as a page.

In Paseo-managed worktree services, use the injected service environment rather than hardcoded root checkout ports.
### Expo Router layout ownership
Each layout owns only the routes directly inside its directory. In the root
layout, register `h/[serverId]`; do not register host leaf routes such as
`h/[serverId]/workspace/[workspaceId]`, `h/[serverId]/open-project`, or
`h/[serverId]/index` there. The `h/[serverId]/_layout.tsx` file owns those leaf
routes with its own nested stack and relative screen names:
`workspace/[workspaceId]/index`, `open-project`, `index`, and so on. Expo Router
warns with `[Layout children]: No route named ...` when a layout registers
grandchildren. Treat that warning as a route-tree bug: on native, this shape can
leave a nested index route mounted without its local dynamic params and render a
blank screen.
Do not paper over missing required route params by reading global params in the
leaf. Required dynamic params belong to the matched route. If
`useLocalSearchParams()` misses one, fix the layout ownership.
Keep non-route modules out of `src/app`. Expo Router treats ordinary `.ts` and
`.tsx` files there as routes, which produces `missing the required default
export` warnings and pollutes the route tree. Put shared route policy in
`src/navigation`, `src/utils`, or another non-route directory.
Treat `/h/[serverId]` as the host home route. It resolves to the last remembered
workspace for that host after the workspace-selection store hydrates unless the
host's hydrated workspace list proves that workspace is gone; hosts without a
remembered workspace go to `open-project`.
Keep workspace identity and retention outside native-stack `getId`/
`dangerouslySingular`. Expo Router maps `dangerouslySingular` to React
Navigation `getId`, and `getId` has broken Android native-stack/Fabric by
reordering an already-mounted workspace screen.
### iOS simulator preview service
Paseo worktrees expose the native iOS dev app through the `ios-simulator` service in `paseo.json`. The service URL serves the simulator preview at `/.sim`, so the preview link is `${PASEO_URL}/.sim`.
