* fix(app): keep New Workspace on the active project
New Workspace preselection was falling back to stale remembered host state when multiple hosts existed. Pass durable active-project context from workspace entry points and centralize initial host selection so stale offline hosts cannot steal the form while startup restore remains last-workspace only.
* fix(app): address New Workspace review feedback
* fix(app): stabilize New Workspace host selection
* fix(app): preserve New Workspace host fallback
* test(app): loosen stale-host project assertion
* fix(app): prefer reachable new workspace hosts
* fix(app): avoid stale offline workspace preselect
* fix(app): prefer online project hosts
* fix(app): make new workspace global
New Workspace now opens as an app-wide screen. Host and project context can still preselect the form through query params, but the route itself no longer lives under a host.
* fix(app): simplify new workspace selection
Centralize workspace navigation behind a small route-derived API so the workspace shell reads active selection from the current Expo Router route instead of a separately synchronized store.
Remove the stale layout-driven active-workspace write that regressed web after 02e5b564.
The worktree.new keyboard handler was registered inside ProjectHeaderRow,
which only mounts when the sidebar is open. Register a single global handler
in the app layout keyed off the navigation-active workspace selection.
