✨ feat: implement GOWORK environment handling in buildexec

Add logic to set the GOWORK environment variable in the build execution steps. This helps ensure that the appropriate Go workspace is used during command execution, improving compatibility with Go modules. Additionally, modify the build plan for the "vibeaura" module to check for the existence of the cmd/vibeaura directory, allowing for targeted compilation.
