discord9 5a73f6f21f feat(perf): add nullable_wave distribution and nullable range-fn case ...

Add a nullable_wave value distribution to the direct-SST fixture
generator: every null_every-th sample of each series is NULL, counted
per series so every series carries the same null ratio on every layout.

New case tests/perf/query_cases/promql_nullable_range_fn: 128 series x
780 timestamps at 15s cadence, nullable_table (25% NULL, null_every=4)
and dense_table (identical, 0 NULL) as control. Seven TQL queries cover
rate/increase/delta and count/last_over_time at [5m], rate at [1m],
and a dense control query. Every window of every series takes the
nullable branch (no window is entirely NULL or NULL-free).

Regression evidence for #9234. The case is selectable by explicit path;
not added to DEFAULT_CASES.

Review: .e-agent/greptimedb-query-optimization-review-2026-09-17.md §4.4.
