FEATURE: Add `read_vcd -begin_time`/`-end_time` activity windowing (#466) * Add read_vcd -begin_time/-end_time activity windowing. Limit VCD transition and duty counting to an optional time window so activity annotation can ignore regions outside the interval of interest. Co-authored-by: Cursor <cursoragent@cursor.com> * Format VcdCount::setFilter parameters one per line. Co-authored-by: Cursor <cursoragent@cursor.com> * Address VCD begin/end review: VcdTime, sentinel, rename. Use VcdTime and vcd_null_time instead of int64_t/-1, rename VcdCount filter bounds to begin/end_time, rename the regression to vcd_begin_end_time, and document read_vcd -begin_time/-end_time in ChangeLog.txt.
