chore(visual): gitignore snapshot baselines; sync workplan task IDs

Visual baselines are large binary test artifacts; keep them out of the repo.
They stay on disk locally (regenerate with `pnpm test:visual:update`); the
infra fixes that make rendering deterministic remain committed. Also folds in
the state_hub_task_id writeback from `make fix-consistency`.

     404'ing every relative asset (also broke `pnpm showcase` in the browser).
