Duo workspace toolbars could overlap the native tab bar, hide actions, or duplicate Compose. This layer keeps modal toolbar groups native while moving workspace rail actions away from the tabs, and gives the workspace one Compose action. A pull request opened from a thread also leaves Compose out of its bar.
Verified folded and unfolded landscape on the Duo: PR actions and tabs do not overlap, search opens, and modal search remains usable. Focused header tests and mobile typecheck passed.
This is the first toolbar layer. #23145 later in this stack moves list search to a bottom field and makes header actions update when their contents change. Unfolded portrait is unverified.

Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — This PR substantially changes default search, filtering, and compose placement across Duo folded/unfolded workspace layouts, including native split-column header behavior and transition handling. The stateful UIKit toolbar integration and product-default changes warrant human review.

The iOS workspace header now uses column-aware navigation controls for compose and search. The workspace toolbar selects control placement by device and tab. HomeHeader no longer renders a separate header.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Exclude pull-request routes from detail compose.
When a user opens a pull request from a thread, navigation opens PullRequest without selecting the pullRequests tab. This condition still enables detailCompose, so V5StackHeader adds “New task” beside the pull-request actions. Check the visible detail route as well as selectedTab before supplying onCompose.

✅ Addressed in commit 7153c10
Fixed in 7153c10fce9. Pull request routes (PullRequest, PullRequestFile, PullRequestFiles) now skip detail compose wherever they open, so a pull request opened from a thread no longer gets New task beside its review actions. The selected-tab check still covers the empty Pull requests detail.
@juliusmarminge Confirmed in the supplied code. All three pull-request routes now receive onCompose={undefined}, including when opened from a thread. The selected-tab check still suppresses compose for the empty Pull requests detail.
✅ Review thread resolved.
