test(scanner): require heal pressure evidence metrics (#7392)

Browse Source 
Require scanner/heal ABBA adapters to emit foreground pressure, heal lock wait p99, and heal attempt counters before a measured W10/W11 run can be accepted.

Report per-leg pressure ratios, lock p99 samples, and attempt cost per healed object so synthetic harness runs remain evidence-contract validation rather than performance proof.
