This PR fixes
perspective-viewer-datagridto handlesplit_bycolumns which change due to aTable::updatecall which introduces a new value (or removes all instances of an existing one).In order to implement this fix without requiring the datagrid to fetch all column names for each tick, two breaking API changes are introduced as well:
View::column_pathsnow takes optionalColumnWindowstart_colandend_colbounds.View::column_pathsnow no longer returns__ROW_PATH__as an output column when agroup_byis applied (though this column is still in the output data).Screen.Recording.2025-08-23.at.9.11.39.PM.mov
