…ent build collisions Multiple PRs building the same repo concurrently all wrote to the same default `buildkit` GHA cache scope, causing manifest overwrites and 10GB eviction pressure. Scope cache by image name (+ suffix) so each image gets an isolated bucket while still sharing cache across branches. Also removes the redundant `cache-to` from the GOSS build step — the push step immediately overwrites it, so the GOSS write was pure waste.
