Implement secret masking for command-line logs to prevent sensitive information (e.g., API keys, passwords) passed as environment variables from being exposed in build logs. This includes a new cmd.Mask function and its integration into the project's build helpers.


PR created automatically by Jules for task 3333875199693607752 started by @pellared

This change introduces a `Mask` function in the `cmd` package that identifies
leading environment variable assignments in a command line string and replaces
their values with `[MASKED]`.

The `runExec` helper in the `build` module is updated to use this function
when logging commands, ensuring that sensitive information like API keys or
passwords passed via environment variables are not leaked into the build logs.

Comprehensive unit tests for `cmd.Mask` and a regression test for `runExec`
are included.
