cah b4d5856bf9 data: add SC-LDPC results and comprehensive comparison plots
SC-LDPC threshold saturation results:
- SC original staircase: 2.28 photons/slot (vs 4.76 uncoupled)
- SC DE-optimized: 1.03 photons/slot (vs 3.21 uncoupled)
- Shannon limit: 0.47 photons/slot (remaining gap: 3.4 dB)

Add CLI to sc_ldpc.py (threshold, fer-compare, full subcommands).
Add threshold progression, SC threshold bars, and SC FER plots.
