fix(app): EmptyWorkspaceLanding's titlebar portals render sync-context components at the "/" route — latent crash on every real boot (origin/main) #1458

Status: fixed in PR #1360 (d9bd9da). Filed so it's visible on main independently — this is latent on origin/main right now.

pages/empty-workspace-landing.tsx renders SessionChatsDropdown + StatusPopoverV2 into titlebar portals. StatusPopoverV2 → DirectoryStatusPopover → useSync() — but the "/" route (NewSessionLanding) is never inside a SyncProvider, so the throw kills the whole route tree. Critically, that tree ALSO contains the reactive LandingEffect — so no draft is ever created and the app stays frozen at "/".

Trigger timing: at real boot, workspace projects arrive over the wire AFTER the app mounts, so the no-directory window renders the empty landing briefly on EVERY boot — the crash is not an edge case. Unit tests (new-session-landing.test.ts etc.) mock the contexts and never see it; the e2e fleet rig caught it live.

Fix: drop the two titlebar portals from the landing (chrome dots on a momentary landing); keep the mark + open-folder content.
