cah 41e2ef72ec feat: add SC-LDPC density evolution with threshold computation

Implement position-aware density evolution for SC-LDPC codes:
- sc_density_evolution(): flooding-schedule DE tracking per-position
  error rates, demonstrating the wave decoding effect
- compute_sc_threshold(): binary search for SC-LDPC threshold

Uses flooding schedule (not layered) to avoid belief divergence
from cross-position message interference in the coupled chain.
