Bind each cached loader to a `{@const}` so the `{#await}` blocks keep
the same promise across patch reloads instead of re-running and
flashing their pending branch.
The comment records only that it is resolved, so the name comes from the
resolve operation in the patch's log. Adds the action to timeline
threads too, and shapes the badge like a review's verdict.
