- The heap census also counts instances a class value constructs: the
construct thunk that `newValue` calls counts them after its allocation,
as `new` does at its own.
- A build with SCRIPTC_HEAP_CENSUS set is its own executable cache entry
(`heapCensus` in the early cache's key and route key), and one with
SCRIPTC_REPR_REPORT set does not read the early cache, since a hit
emits no module and so writes no report. The CLI's startup route defers
both to the full compiler.
- Test: a warm cache still builds the census executable, counting
`new` and class-value constructions, and still writes the report.
