[BUG] Deployment succeeds but action fails with: "supplied version is the current active version"

Workflow:

- uses: FirebaseExtended/action-hosting-deploy@v0

Observed behavior:

1. Hosting version is created successfully
2. Files upload successfully
3. Version is finalized successfully
4. Site updates correctly
5. Action exits with code 1

Error:

FAILED_PRECONDITION

Can't release to
projects/-/sites/slide-cube-3/channels/live:

supplied version
projects/.../versions/xxxxxxxx
is the current active version

Expected behavior:

If the version is already active, the action should either:
- treat it as success, or
- treat it as a no-op deployment,
instead of failing the workflow.

firebase-tools version:
15.22.3

Start by reproducing the GitHub Actions workflow with firebase-tools 15.22.3 and confirm that hosting creation, upload, finalization, and site updates complete before the release step fails. Trace the deployment result handling, then verify that an already-active version exits successfully or is treated as a no-op without masking real failures.
