Variet Agent d61c538308 fix(critical): complete Zt sign alignment across all modules ...

Fixed ALL instances of (d - sqrt_rho*z) -> (d + sqrt_rho*z):
- models/vasicek.py: conditional_transition_matrix() (used by lifetime PD)
- data/transition_matrices.py: _generate_model_consistent_matrix()
- models/credit_cycle.py: already fixed in previous commit

Added sign convention docs:
- vasicek.py conditional_pd() uses Basel convention (Z↑=loss↑)
- conditional_transition_matrix() uses Belkin convention (Z↑=호황)
- Both conventions documented in module docstrings

Pipeline 8/8 validation pass after fix
