The global Alt+Left/Right keydown handler called preventDefault() on the
browser's Back/Forward shortcut for the whole document — the most likely
cause of "can't switch workflow" after the previous deploy, and a poor
default regardless. Remove the handler (stepToSnapshot remains for a
future conflict-free binding or a timeline button).
Also wrap the post-switch baseline seeding in try/catch so any failure
there can never propagate into ComfyUI's openWorkflow action and block a
workflow switch.
