IA: no global search, no cross-tab discovery, no onboarding for non-terminal screens

IA Review Summary — 7.5/10

Architecture is sound (5 tabs, flat push navigation, URI deep link router) but has three key gaps:

1. No global search

Four separate search surfaces exist but are siloed:

Search	Scope	Entry
Event Search	Team events	Me Tab AppBar icon
Transcript Search	Session FTS	SessionsScreen AppBar
Settings Search	Local filter	Settings page inline
Project Filter	Project list	ProjectsScreen

None of them cross domains. A unified search bar accessible from the top of any tab would dramatically improve discoverability.

2. No onboarding outside terminal

Only onboarding_overlay.dart (terminal 6-card carousel) and help_sheet.dart (tmux cheat sheet) exist. Projects, Me, Steward, Attention/Approvals have zero contextual guidance.

3. Cross-tab navigation is invisible

The URI router supports termipod://project/<id>/... etc. but this is only discoverable via deep links and agent-driven navigation. Normal users have no way to jump from a Settings entry to the relevant Project, or from an Activity event to the source screen.

Suggested fixes

• Unified search bar in AppBar across all tabs, indexing events + transcripts + settings + projects
• Coach mark tour for first-time Me/Projects usage
• Cross-tab deep link chips in Activity feed entries
