Fall-through data threshold lowered 32 → 24

Concern: Iter 25's [DATA-AS-CODE] diagnostic on Asteroids still emitted 5 spans of small data overlap (8-30 insns each). The 32-byte minimum-region threshold for _is_high_confidence_data was conservatively chosen against the 1900 → 21 collapse risk, but the resulting cutoff missed a few legitimate data tables (notably a 30-byte POINTER_TABLE at ROM 0x09EA-0x0A08, just below the bar).

Raw traces, ROM material, local paths, and personal data are not part of this public record.
