Move case/storage thresholds out of the main summary table into a
collapsible <details> block below it, so measured cases render one row
per query instead of an extra Query=N/A storage row that stretched the
table. Drop the backtick code span around the status cell (the escaping
in text() turned it into a visible backtick) and unify multi-threshold
separators on '; '.
- query-regression-comment.cjs: classifyThresholds shared helper,
syntheticThresholdDetail for case-level thresholds, kind marker on
synthetic rows, renderThresholdDetails emitting unescaped details tags
with text()-escaped entry content, plain-text status cell
- query-regression-comment.test.cjs: updated separator/kind assertions,
new test covering details-block rendering and plain-text status
