sonarqube: auto-detect newest CUDA env file per branch

[rgsl888prabhu]

The nightly main scan has been failing since 2026-05-15 because PR #1198 bumped main from CUDA 13.1 to 13.2 (replacing all_cuda-131_arch-*.yaml with all_cuda-132_arch-*.yaml), but run-sonar-analysis.sh still pointed at the deleted 13.1 yaml.

Detect inside the per-branch loop: glob conda/environments/, version-sort, take the newest. release/26.04 keeps using cuda-131 (still on disk there); main now picks cuda-132 automatically; future bumps need no script change. Loud failure if no matching env file exists at all.

📝 Walkthrough

Walkthrough

The SonarQube analysis script shifts from hardcoded conda environment setup at startup to dynamic selection. CPU architecture is detected once, then per-branch conda environment YAML files matching that architecture are discovered, sorted by version, and the newest is selected. Missing candidates are logged and skipped gracefully.

Changes

Dynamic conda environment selection by architecture

Layer / File(s)	Summary
Dynamic conda environment selection by architecture sonarqube/run-sonar-analysis.sh	CPU architecture is determined at startup and used to discover matching all_cuda-*_arch-${ARCH}.yaml candidates within each cloned branch. The newest version-sorted candidate is selected; if none exist, the branch failure is recorded and processing continues to the next branch.

Check name	Status	Explanation
Title check	✅ Passed	The title accurately summarizes the main change: auto-detecting the newest CUDA environment file per branch instead of hardcoding a single version.
Description check	✅ Passed	The description clearly explains the problem (CUDA version bump broke hardcoded reference), the solution (auto-detect newest env file per branch), and expected behavior for different branches.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
