chore(deps): update telemetry and patch dependencies for release

[danielkov]

Summary

Update opentelemetry to 0.32.0 and tracing-opentelemetry to 0.33.0, alongside patch updates for reqwest (0.13.5), diffy (0.5.2), and which (8.0.6). Prepare patch releases for the seven crates whose direct dependency requirements change.

Technical details

Raise the shared reqwest minimum to 0.13.5. The diffy and which updates are transitive lockfile-only changes; the OpenTelemetry upgrade also removes the now-unused SDK and its random-number dependencies.
