* fix(app): validate persisted client state
Persisted replica data could satisfy TypeScript through an assertion while missing fields required by renderers. Treat every AsyncStorage value as untrusted input, clear values that fail strict schemas, and version the replica DTO so incompatible caches cannot hydrate.
* fix(app): preserve validated legacy state
* fix(app): preserve validated preferences
Preserve supported legacy location fields and every shipped theme while keeping unknown persisted fields rejected. Align browser test seeds with the current preference shape so strict validation exercises the intended provider.
* fix(app): migrate legacy agent preferences
Released clients stored host/location fields and per-provider thinkingOptionId together. Migrate those exact strict bytes into current preferences without admitting unknown fields.
* fix(app): preserve drafts with legacy reviews
Accept the exact strict shape released for workspace review attachments so migration can discard that obsolete attachment without clearing every persisted draft.
* fix(app): align turn footer actions
Keep running-turn actions in the same position as completed-turn actions and use the shared small icon size for both copy and fork controls.
* feat(app): improve sidebar workspace identity
Make dense sidebar workspace rows easier to scan and let each device control how connected hosts are identified.
* fix(app): keep host badges readable
Use a compact display menu and keep identity color on the host icon so translated controls fit and badge text retains standard contrast.
* fix(app): announce selected sidebar badge mode
* fix(app): retain icon-only host names for screen readers
* fix(app): name hoisted workspace rows
* fix(app): retain host identity in workspace labels
* fix(app): retain workspace status in row labels
* fix(app): defer host appearance until identity resolves
* fix(app): serialize host appearance writes
* fix(app): serialize host registry writes
* fix(app): bound sidebar host badge labels
* test(app): match workspace status labels
* fix(app): consolidate sidebar identity behavior
* test(app): assert status grouping behavior
* fix(app): keep sidebar row actions accessible
* fix(app): stabilize optimistic message layout
