Flutter Sprint Timeline Card with Offset Gantt Task Bars

A project schedule card where each task bar starts on a different day and runs a different length against one shared date axis, so overlap and slack are visible without a chart library. Five staggered bars plus a release milestone marker, positioned with fixed-pixel spacers inside a Wind row.
