Keep the page chrome sync helpers in shell-bridge.js so React and legacy routing share one implementation.
This preserves the sidebar breadcrumb and discover download bar behavior without shadowing the legacy shell helpers in init.js.
- keep getCurrentPageId off the legacy shell bridge surface
- leave page-id lookup on the router side where it is actually used
- align the bridge tests and type definitions with the slimmer API
- Route Issues to the React host even while the shell is still booting
- Ignore stale bootstrap work when navigation changes mid-load
- Clear artist-detail state when leaving the page so browser back can reach Library
- Add smoke coverage for the artist-detail back-navigation path
- Re-sync the active shell page on popstate
- Keep React routes like /issues on the React host after back/forward navigation
- Preserve the existing legacy page activation path for non-React routes
- Expose SoulSyncWorkflowActions from the shell bridge
- Route album download and wishlist actions to the legacy modal helpers
- Fall back to showToast for workflow notifications
- Unblock the issue modal download button by wiring the real host contract
