Tags give the ability to mark specific points in history as being important
v0.5.3 - Add entry_indices to GroupedReportRow, so callers (e.g. the deferred webapp expand-by-group view) can look up a group's underlying entries without recomputing the grouping key - Library-only change, no CLI-visible behavior
v0.5.2 - report --tag now squashes to one row per period by default (was: one row per exact tag combination) - New --unsquash flag restores the previous per-combination breakdown
