feat(mobile): polish session preferences and transcript

[iscekic]

Summary

• Add persisted Preferences for reasoning expansion and session screen wake behavior.
• Group transcript time markers and remove repeated per-message labels.
• Show complete tool output in tool detail cards.

Why

The session UI repeated timestamps, hid long tool output, and lacked persisted controls for session behavior.

How

• Reuse the SecureStore preference helper and clear both settings on sign-out.
• Build time markers and visibility filtering in the pure transcript builder.
• Remove tool-card output caps while preserving mono scrolling and truncation support.

Verification

• pnpm format
• pnpm typecheck
• pnpm lint
• pnpm check:unused
• Focused mobile tests: 12 files, 105 tests passed.
• Full mobile test suite before main merge: 355 files, 3408 tests passed.
• Full mobile test suite after main merge repairs: 368 files, 3611 tests passed.
• iOS E2E: all six scenarios passed on ses_20910801062d332d33798ca7cb.
• Wake-lock semantics remain covered by session-keep-awake.test.ts; the operating-system idle timer is not observable in the simulator.
• Sign-out cleanup remains covered by auth-context.test.tsx and the deferred SecureStore read regression test.

E2E

E2E: bot-e2e — iOS-only verification completed. The 300000-character sheet opened within the decision threshold, so no safety cap was added. The final-head re-verification passed after the main merge.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Executive Summary

Incremental review of the 4 files changed since the previous review (merge conflict resolution with main's auth hardening plus a test-mock fix): the PR's clearKeepScreenOnPreference sign-out clear was correctly re-applied on top of main's refresh-token rewrite, the sonner-native test mock and hoisted preference mocks are sound, the AppState subscription retains proper cleanup (no memory leak), and no new issues were found.

Executive Summary

Reviewed all 41 changed mobile files covering persisted session preferences, transcript time markers with visibility filtering, and uncapped tool output; the visibility extraction was verified line-by-line against the renderers it mirrors, the sign-out race fix is correct, and no memory leaks, dangling references, or logic errors were found.
