Code protocol bug fixes and improvements

[tarunKoyalwar]

Proposed Changes

• fix flakiness when loading and executing code protocol templates in windows environment ( observed by @princechaddha in win with low spec with powershell engine )
• improve debug mode in code protocol to dump actual output and the internal command being run , this increases visibility and outputs entire response instead of default behaviour of only showing output which causes confusion and has less observability when debugging
• depends on Improve debugging and use LookPath gozero#18
