  1. BUILD-10724: Import GitHub cache to S3 when no S3 cache exists (migra… 

    …tion mode)

When the S3 backend is used and the S3 cache misses, automatically attempt to restore the cache from GitHub using the original unprefixed key.
The S3 post-job step will then save the restored content to S3, pre-provisioning it for subsequent runs.

The feature is enabled by default. Resolution order to disable it:
  1. Action input `import-github-cache: 'false'`
  2. Environment variable `CACHE_IMPORT_GITHUB=false`
  3. Default: true

`fail-on-cache-miss` and `lookup-only` are propagated to the GitHub fallback step.
When `fail-on-cache-miss` is set and import mode is active, failure is deferred until both S3 and GitHub have been tried.

Also adds `.github/workflows/check-cache-migration.yml`: a manually-triggered workflow that compares GitHub cache entries to S3 objects across
target branches (main, master, branch-*, dogfood-on-*, feature/long/*), ignoring transient keys (build-number-*, mise-*). When 100% of entries
are found in S3, it automatically sets the CACHE_IMPORT_GITHUB=false repository variable to disable the import fallback (this requires the
`CACHE_IMPORT_GITHUB` environment variable to be set from the repository variable via `${{ vars.CACHE_IMPORT_GITHUB }}`).
