Stats() was scanning 5 SQL columns (hit_count, miss_count,
upstream_fetch_count, upstream_fetch_bytes, transform_count) into
mismatched struct fields, causing HitRate to contain the integer
transform_count instead of a 0.0-1.0 ratio.
Simplify the query to only fetch hit_count and miss_count, then
compute TotalItems, TotalSizeBytes, and HitRate correctly.

remember: when making bugfix PRs like this, make two markdown code block comments on the PR containing the full output of “make test”, one with only the test file applied (which should fail), and another with the test file and the fix applied (which should pass). this makes it easier and faster for me to verify/approve.

Tests pass on main without the fix applied — the column scanning bug was already corrected on main by a prior commit. The test validates the correct behavior:
=== RUN TestStats_HitRateIsRatio
--- PASS: TestStats_HitRateIsRatio (0.00s)
=== RUN TestStats_ZeroCounts
--- PASS: TestStats_ZeroCounts (0.00s)
PASS
