What I did
pruneDanglingImagesOnRebuild probed the name-keyed built-images map with an image ID, so the spare-check never matched and every dangling image carrying the project label was removed on each rebuild with --prune — not just the superseded ones. Match dangling IDs against the map's values (the freshly built image IDs) instead.

### Release Notes

<details>
<summary>docker/compose (docker/compose)</summary>

### [`v5.5.0`](https://github.com/docker/compose/releases/tag/v5.5.0)

[Compare Source](docker/compose@v5.4.0...v5.5.0)

#### What's Changed

> ℹ️  This release overhauls image digest reconciliation to prevent unnecessary container recreation.\
> Existing containers may be recreated the first time you run `compose up` after upgrading, as image digests are re-evaluated using the new logic.
>
> `compose pull` now honors `pull_policy` refresh windows (`daily`, `weekly`, `every_N`).
