Fix input forwarding from input-prefixed parameters

cole-rgb · cole-rgb · commit 747489abaaba · 2025-03-16T13:54:28.000-05:00
- Fixed input name normalization to properly convert between underscore (_) and hyphen (-) formats
- Properly set environment variables for nested actions by converting hyphens to underscores
- Added more detailed diagnostics for input handling
- Updated local testing script to verify input forwarding logic
- Ensured both the action reference and direct command modes handle inputs consistently
