Document and validate Dockerfile versions

[Copilot]

Verified all Dockerfile versions are current stable releases (Go 1.25, Delve 1.25.2, SUSE SLE15:15.7). Added documentation and validation infrastructure for future version management.

Changes

• Dockerfile: Added inline comments documenting current versions and verification date. Incremented DELVE_DEBUGGER_VERSION 0→1.

• Version tracking (package/VERSIONS.md): Documents all component versions, sources, and update policy.

• Build documentation (package/README.md): Complete reference for building, testing, and updating the image.

• Validation script (package/test-dockerfile.sh): Automated testing that extracts version numbers, validates syntax, and optionally performs full Docker build.

• CI workflow (.github/workflows/validate-dockerfile.yml): Runs validation on PR changes to package/ directory with multi-arch build test.

• Security: Added explicit permissions blocks to GitHub Actions workflows per security best practices.

Validation

$ ./package/test-dockerfile.sh
=== Delve Debugger Dockerfile Test ===
  GO_VERSION: 1.25
  DLV_VERSION: 1.25.2
  DELVE_DEBUGGER_VERSION: 1
✓ All validation checks passed

The Makefile now builds images tagged as 1.25.2-1 reflecting the incremented internal version.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
