+ * Publish binary release assets to OSS entirely from the CI runner:

+ * No external FC is involved anymore; CI is the single writer.
+ *
+ * Flow:
+ *   - Every mode uploads its assets to `<prefix>/<tag>/<basename>` (channel
+ *     builds include the rolling `channel-<name>/<name>.json`).
+ *   - After upload, every object is HEAD-verified against the local byte size
+ *     (reconciliation — the runner has the ground-truth artifacts on disk).

+ *     (compareVersions), rewrite `<prefix>/manifest.json`. Channel/prerelease
+ *     never touches it — same semantics the FC sync-release used to enforce.
+ *
+ * Zero-dependency: OSS V1 header signature (HMAC-SHA1) over plain fetch.
