This gives CI pipelines explicit control over E2E test execution. + #### Fixed - Fixed HTML report Timestamp column being truncated on macOS in [`HtmlReportGenerateService`](Services/HtmlReportGenerateService.cs). The column was declared `width: 16em` with `overflow: hidden`, which clipped the dual-timestamp format `[YYYY-MM-DD HH:MM:SS → YYYY-MM-DD HH:MM:SS]` (~300 px) on macOS due to its wider font metrics (SF Pro), while Windows happened to fit. The fix widens `col.col-ts-g` from `16em` to `22em` and removes the redundant `width: 16em` and `overflow: hidden` declarations from `td.col-ts`, relying on the `` width and `white-space: nowrap` to keep timestamps on one line without clipping. Updated the CSS assertion in [`HtmlReportGenerateServiceTests`](FolderDiffIL4DotNet.Tests/Services/HtmlReportGenerateServiceTests.cs).
