Pull request overview
This PR refines the plugin timing warning feature by filtering out plugins with durations less than 1 second from the timing reports. This reduces noise in timing warnings by focusing only on plugins that have a meaningful impact on build performance.
Key changes:
- Updated the threshold calculation to ensure plugins must have at least 1 second total duration to be included in timing reports
- Refactored the
get_plugin_timings_infofunction for improved clarity with explicit early returns - Updated documentation to reflect the new 1-second minimum threshold requirement
