v0.1.9

Released at 2026-08-03

• FEATURE: vmestimator: add __label__ pseudo-label for group_by. It estimates unique values per label name, making it easy to spot high-cardinality labels like trace_id or user_id. Can be combined with explicit keys, e.g. ["job", "__label__"]. See #26.

• BUGFIX: vmestimator: fix snapshot merging collision when multiple estimators share the same group_by keys but use different interval values. Previously, snapshots from such estimators were incorrectly merged into a single entry, causing the interval of one to overwrite the other.
