remove unused hack/lib.sh

[xrstf]

Summary

This file was added a long time ago to support running the CRD generator in a container, to make it immune against GOPATH shenanigans.

The CRD generation has since then long been renewed and doesn't rely on such hacks anymore, but the lib.sh was never removed. It is entirely unused though.

Summary by CodeRabbit

• Chores
  • Removed internal build utility library. This maintenance change consolidates build infrastructure and eliminates deprecated helper functions. Systems relying on these internal utilities will require updates to use alternative approaches or direct implementations.

📝 Walkthrough

Walkthrough

The hack/lib.sh file, a comprehensive Bash utility library spanning CI/CD workflows, Kubernetes operations, Docker management, dashboard operations, and logging utilities, has been completely removed from the codebase.

Changes

Cohort / File(s)	Change Summary
Library Removal hack/lib.sh	Deleted entire Bash utility library containing 27 functions including worker name normalization, retry logic with JUnit integration, containerization helpers, SSH/Vault authentication, dashboard operations, trap management, Kubernetes/Docker orchestration, and logging utilities.

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~45 minutes

• Verification that no remaining scripts or workflows depend on the removed utility functions
• Confirmation that CI/CD pipelines continue to operate without these utilities
• Validation that container orchestration, Docker initialization, and deployment readiness checks are properly handled elsewhere or no longer required
• Assessment of impact on dashboard management and tag verification workflows
• Confirmation that retry logic, logging, and metric collection have been replaced or are no longer necessary

Poem

A library of helpers, once vital and vast,
Makes way for the future, releasing the past.
Simplified pathways, dependencies cleared,
The toolkit evolves as the new code appeared.
