Issue #, if available:

Description of changes:

The publish job in runtime-interface-client_merge_to_main.yml has been failing on main (for example run 39420007852) while publishing nothing. This PR removes it. The coverage jobs in the same workflow are unchanged.

Why it fails

The job runs make build: all four native variants (glibc and musl, x86_64 and aarch64) on one x86_64 runner, with aarch64 under QEMU. The JNI build pulls amazonlinux:2 and alpine:3 anonymously from public.ecr.aws, and that pull is what fails:

public.ecr.aws/docker/library/alpine:3: failed to resolve source metadata ... failed to copy

Why it publishes nothing

The three steps after the build (AWS credentials, CodeArtifact properties, make publish) only run when the ENABLE_SNAPSHOT secret is set. They were guarded this way in #504 (August 2024). Neither ENABLE_SNAPSHOT nor the AWS_ROLE / CODE_ARTIFACT_* secrets those steps need exist in this repository, so every run skips them. What we found:

• All 19 runs from April 2026 to now skipped the Publish step. Older runs no longer have step data, and none are retained before September 2025.
• The snapshot repository this was set up to feed has had no new RIC snapshot since December 2022.

Why the build is not needed here

• The PR build check already builds the same four variants, on native runners (make build-<arch> covers glibc and musl per arch).
• The coverage jobs in this workflow rebuild them on every merge to main.

Also removed

Everything that only served this job: ric-dev-environment/ (publish_snapshot.sh, the CodeArtifact Makefile include, settings.xml, the snapshot-jar check), the publish and test-publish Makefile targets, and the ci-repo Maven profile.
