uv(pass-a-r1): 10000x test coverage — races, edges, seams, fuzz.

20 new tests: thread-safety, tripwire invariants (no cumulative drift), poison,
compat seam (reconcile_ok==tripwire_ok), mutation litmus (grep-based K-field ban),
Hypothesis fuzz (500 random streams), vendor drift gate.

Fix: apply_balance_update now resets tripwire_ok=True (non-fill events default healthy).
26 total (20+6).
