Description

Fixes the VS Code extension webview after importing legacy Roo Router settings. When import downgrades the selected profile into an unconfigured state, Zoo now routes the user into Providers settings from any gated tab instead of trapping the whole shell on the welcome screen, keeps Settings plus Marketplace available for recovery, keeps Chat plus History gated until setup is complete, and treats settingsImportedAt as a one-shot host event so later sidebar relaunches do not replay an old import redirect.

Regression coverage now spans the webview tab-state matrix across Chat, History, Settings, and Marketplace plus a focused import/export host test that proves the import timestamp is posted once during the import sync and then cleared.

Test Procedure

• pnpm --dir src test core/config/__tests__/importExport.spec.ts
• pnpm --dir webview-ui test --run src/__tests__/App.spec.tsx
• pnpm --dir apps/web-roo-code test

1 issue outstanding: platform-unit-test (windows-latest) is still pending after the 10-minute CI watch window. See task

• History is no longer gated while setup is incomplete, so the title-bar History action can still clear and rehydrate task state through showTaskWithId.
• platform-unit-test (windows-latest) was still pending after the 10-minute CI watch window.
• The import redirect still only fires from the chat tab, so imports that arrive while another gated tab is selected can still leave the user stuck on WelcomeView instead of routing into Providers settings.

Addressed the latest sidebar-lifecycle follow-up in 82d35cf0f.

• importSettingsWithFeedback now clears provider.settingsImportedAt immediately after the import-driven postStateToWebview(), so the timestamp behaves as a one-shot host event instead of persisting across sidebar relaunches.
• Added focused regression coverage in src/core/config/__tests__/importExport.spec.ts to prove the timestamp is posted once during the import sync and then cleared.
• Refreshed the PR proof with screenshots showing the first downgraded import redirecting into Providers settings and a later sidebar relaunch staying on Welcome without replaying that redirect.

I did not find a new unresolved review thread to close from this follow-up. Current PR state is REVIEW_REQUIRED, and platform-unit-test is still running on both Ubuntu and Windows.
