Pipeline wiring: - vcn_compute_substrate.py: Delta+RLE → RS ECC → ChaCha20 now in live path - encode_braid_strand/crossing/mountain_merge accept key + compress params - New CLI: encode_enhanced/decode_enhanced for full pipeline - 67/67 tests pass FPGA synthesis: - q16_lut_core → Tang Nano 9K (GW1NR-9C) - 266 LUTs, 68 FFs, 2 DSPs, 1 BRAM - 3.4MB bitstream (q16_lut_top.fs) - Constraint file + build script + wrapper module
