What
Hash list scalar values from their logical length, validity, and recursively hashed elements instead of physical ArrayData metadata. This keeps equal list scalars backed by independent arrays or slices on the same hash path.
Tests
go test ./arrow/scalar ./arrow/array -count=1GOOS=linux GOARCH=386 go test -c -o /dev/null ./arrow/scalarpre-commit run golangci-lint-full --all-filesRegression coverage includes independent backing arrays, zero-copy slices with different offsets, extra leading/trailing values, and different validity bitmap padding.
