Same-document navigations now commit synchronously in WebContent, while the UI process mirror learns about them over asynchronous IPC. A stale UI seed could be accepted back into a live non-initial document and overwrite its latest entry, making queued traversals target unreachable entries. Share descriptor comparison helpers between LibWeb and LibWebView. Reject stale top-level seeds against the active document latest entry, and let the UI process adopt WebContent current snapshots when a seed is rejected. Test-only session history dumps now first send WebContent current state synchronously, so dumps observe the converged state. Allow post-load UI seeds to carry UI-owned nested histories that the freshly loaded top-level document has not reconstructed yet. Add unit coverage for matching those seeds while still checking top-level state.
