Ship a reviewed hot fix ahead of a long-running review loop

When a feature branch bundles one urgent, already-reviewed fix (here a viewer crash) with a larger change still going through repeated review rounds, cherry-pick just the urgent fix's test and fix commits onto the current main branch. Re-run its test red without the fix and green with it on that base, then push them alone. Each review round on complex state-machine code (reload or undo races) tends to find new edge cases, so bundling holds the urgent fix back for hours. Also tell the other agents that pushes are serialized behind green CI, or their follow-up pushes cancel the hot-fix build.
