PR #356 (Renovate) failed with "Artifact file update failure" because
go.sum was out of sync with go.mod's replace directives: the require
section referenced v0.17.0 for otel/log packages while the replace
directives pinned v0.19.0, but go.sum only had hashes for v0.16.0.
This commit:
- Bumps otel/otel, otel/trace, otel/sdk to v1.44.0
- Updates all related otel exporters and sub-packages to v1.44.0/v0.20.0
- Aligns replace directives from v0.19.0 to v0.20.0
- Fixes require section to match replace targets
- Adds all missing h1: and go.mod hashes to go.sum
- Also bumps grpc v1.79.3→v1.80.0, proto/otlp v1.9.0→v1.10.0
Closes#359
