fix(mu-debt): Fix 6 pre-existing test failures + VIBEE enum codegen

MU-ДОЛГ items resolved:
1. quantum_transition.zig: Fix DefaultPrng temp pointer, const→var for
   deinit, i3 type annotation for runtime shift, random vectors in test
2. riemann_gamma.zig: Add Lanczos gamma function + functional equation
   for ζ(s) at Re(s)<0 — fixes ζ(-1)=-1/12 divergence
3. efficiency_benchmark.zig: Fix boundary conditions (≤/≥), remove
   false quaternary>ternary assertion
4. vibee_parser.zig: Add parseInlineEnumArray for enum: [...] syntax
   — PredictionStatus now generates as proper enum
5. lisa_predictions.zig: Regenerated with correct enum + real function
   signatures (std.math.pow 3-arg, scientific notation constants)
6. tests_gen.zig + emitter.zig: Remove debug prints, cleanup

All 76/76 tests pass across 6 previously-failing files.
