🛠️ Bug fixes

Fixed a network channel concurrency issue that could cause out-of-order messages and slower writes.
Disabled a parallel runtime planner behavior that could increase memory use for some variable-length patterns. Re-enable per query with
CYPHER parallelRepeatHeuristic=enabled
.
Fixed
COUNT(DISTINCT)
overcounting in the pipelined runtime.
Auth rules with invalid time functions now fail at creation time.
Fixed
stDev()
returning 0 instead of null for empty input.
