Pull request overview
This PR modernizes the base image support by removing legacy Linux distributions (Debian bookworm, Ubuntu focal/jammy) and standardizing on GCC 14 and Clang 20 across all remaining supported distributions (Debian trixie and Ubuntu noble). The upgrade to Clang 20 supports the introduction of new flang and prevents toolchain mixing issues.
Key Changes:
- Removed support for legacy distributions: Debian bookworm, Ubuntu focal, and Ubuntu jammy
- Standardized GCC version to 14 and Clang version to 20 across remaining distributions
- Retained only Debian trixie and Ubuntu noble as supported base images
