Route app auth through workspace client

CHANGELOG.md

@@ -5,6 +5,7 @@
 - Recorded the active development direction: use the local HotView/hot-reload setup for iterative app work and defer web/local builds and hosted deployment unless explicitly requested.
 - Started Phase 4 shared app core cleanup by adding an explicit `StudyDataClient` contract and browser/Tauri data adapters behind the existing study client API.
 - Added explicit workspace/auth client contracts so local HotView storage and hosted workspace persistence sit behind the same app-core boundary.
+- Routed the app shell's hosted-login checks through the auth client instead of reading the hosted environment flag directly.

-Current foundation note: `src/studyDataClient.ts` now defines the app-level resource/query contract, and `src/studyClient.ts` routes existing UI calls through browser and Tauri adapters. `src/workspace.ts` also defines workspace/auth client contracts so local HotView storage and hosted persistence share the same app-facing boundary. The browser adapter still owns the HotView JSON/JSONL package loading path, but the UI no longer needs to know which adapter is active.
