Implemented a Mask function in the cmd package to sanitize command line strings by masking leading environment variable values. This enhancement is integrated into the build pipeline's runExec helper to prevent sensitive information from being exposed in build logs. The change is fully tested with new unit and integration tests.

Implement a `Mask` function in the `cmd` package that replaces the values of leading environment variable assignments in a command line string with `[MASKED]`. This helps prevent secret leakage in logs.

Integrate `cmd.Mask` into the `runExec` helper in the `build` package to automatically sanitize command line strings before they are logged to the output.

Add unit tests for the `Mask` function and an integration test in the `build` package to ensure the masking logic works correctly.
