Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to This change attempts to disable HTTP/2 globally, but cached transports may ignore the setting, so the intended network behavior may not consistently take effect. The PR is not merge-ready until HTTP/2 is configured per transport or the global toggle is made safe and reliable. 🚥 Pre-merge checks | ✅ 15✅ Passed checks (15 passed)

- Around line 121-122: Remove the process-wide DISABLE_HTTP2 environment toggle
around the manifest transport setup. Configure HTTP/2 directly on the transport
returned by rest.TransportFor instead, ensuring the resulting transport has
HTTP/2 disabled without relying on cached transport behavior.

Avoid the process-wide DISABLE_HTTP2 toggle.
rest.TransportFor can return a cached transport whose cache key excludes DISABLE_HTTP2. This toggle therefore does not reliably disable HTTP/2. Configure HTTP/2 per transport instead. If the toggle remains, preserve and restore the prior value, serialize access, and handle both environment-operation errors.
