…s their results

The v0.4-preview binary embeds one hand-written kernel per ClickBench query
(crates/gravity/backend/irprobe/src/q00.rs ... q36.rs), plan matchers named
after the benchmark queries, and a cross-query cache of filter verdicts that
makes the hot runs replay the answer of the previous run without touching data.
Trivially perturbed queries such as SELECT MIN(URL) FROM hits are refused with
an error. See the pull request description for the details.
