Enhance CLI Build Duration Output with Human-Readable Formatting (#4591)

* Use humantime for build duration formatting in CLI

Replaces manual millisecond formatting with humantime::format_duration for improved readability of build duration logs. Adds humantime as a dependency in Cargo.toml.

* Format build duration with millisecond precision

Changed build duration logging to use millisecond precision instead of default formatting to avoid microsecond/nanosecond noise.

* Refactor duration formatting to use helper function to reduce code duplication.
