test(jelly-micro): add per-fixture recall floors

Replace the trivially-passing recall >= 0 gate with a RECALL_FLOORS
map keyed by fixture name.  Fixtures that already reach 100% are locked
at 1.0; partially-resolved fixtures (classes, defineProperty, super,
super2) are locked at their current baseline so a single lost edge fails
CI.  Unresolvable fixtures (0% baseline) continue to default to 0.

Closes #1387.
