What Changed

• Modified the environment variable key normalization in the "Parse Workflow Inputs" step to convert hyphens to underscores using tr '-' '_'
• Updated all environment variable references throughout the workflow from hyphenated format (e.g., INPUT_setup-result) to underscore format (e.g., INPUT_setup_result)
• Added a comment explaining the normalization: "Note: Replace hyphens with underscores in keys for GitHub Actions expression compatibility"
• Applied the normalization to both ALL_INPUTS and TIMING_DATA parsing loops, affecting variables prefixed with INPUT_ and TIMING_

Why It Was Necessary

• GitHub Actions expressions do not support hyphens in environment variable names, causing potential reference failures
• Standardizing on underscore-separated variable names ensures compatibility with GitHub Actions expression syntax
• Prevents runtime errors when accessing environment variables containing workflow results and timing data

Testing Performed

• Verify workflow runs successfully with the normalized environment variable names
• Confirm all job status checks properly evaluate using the underscore format (setup_result, test_magex_result, pre_commit_result, etc.)
• Validate that timing data and input parsing correctly populate environment variables with normalized keys

Impact / Risk

• Breaking Change: None - this is an internal implementation change within the workflow
• Risk: Low - affects only environment variable naming convention within this workflow file
• Compatibility: Improves GitHub Actions expression compatibility and prevents potential variable reference errors
