Pull request overview

This PR addresses release pipeline failures by ensuring release artifact generation uses the correct host build parameters and by correctly passing Docker Hub credentials into reusable publishing workflows.

Changes:

• Update make docker-generate to set GOOS/GOARCH explicitly when running go generate.
• Pass Docker Hub token into reusable Docker publish workflows from release.yml.
• Declare DOCKER_TOKEN_EBPF_INSTRUMENTATION as a required workflow_call secret in the reusable Docker publish workflows.
