Mobile: theme setting + session row unification

[iscekic]

Summary

Two client-only mobile features:

1. Theme setting (Light / Dark / System)

• Adds a persisted theme-preference (default System, survives sign-out) via the existing createSecureStorePreference.
• Applies globally through a single Appearance.setColorScheme(...) call, which drives NativeWind className tokens, useThemeColors()/useNavigationTheme(), the status bar, and every other useColorScheme() consumer — so use-theme-colors.ts is untouched.
• No cold-start flash: RootLayoutNav holds the splash until the stored preference has loaded and been applied (the apply effect runs before SplashScreen.hideAsync()).
• New Appearance section on the profile screen with a System/Light/Dark segmented control (new dependency-free SegmentedControl), reflecting the stored preference and firing a selection haptic on change.

2. Session row unification

• Parameterizes the shared StoredSessionRow/RemoteSessionRow wrappers with variant ('list' | 'card') and interactive, and migrates the Home "Agent sessions" section onto them so Home and the Agents list render through the same wrappers.
• Home rows keep their card tiles and stay tap-only (no long-press manage menu); they now show the git-branch subtitle, needs-input dot, and meta.
• Canonical repo-name-first eyebrow on both screens (repo name when a git URL is present, platform fallback otherwise). This intentionally changes the Agents list eyebrow from platform-only to repo-name-first.

Intended behavior changes

• Agents list eyebrow: platform-only → repo-name-first.
• Home stored-row meta: now updated_at-based.
• Home active rows: now show a live dot + relative time (was a live dot only).

Non-goals

No backend/tRPC/schema/shared-package changes, no new theme tokens, no long-press menu on Home, no new dependencies.

Testing

• pnpm typecheck, pnpm lint, pnpm check:unused, pnpm format:check, pnpm test (1678 passing) all green.
• On-device E2E (iOS): theme force Dark/Light, cold-relaunch persistence, System with a live OS light→dark flip; Home card rows (repo-name eyebrow + git branch + needs-input + meta, tap-only) and Agents list (repo-name eyebrow, long-press manage, a11y).
