fix: preserve semantic differences in refactored shared utilities

- q16_lut_generator.py: revert to local unsigned-wrapping Q16 functions
  (hardware LUT uses 32-bit wrapping + 0xFFFFFFFF div-by-zero sentinel)
- dataset_ingest_rds.py: import load_json (not load_jsonl) — files are
  standard JSON arrays, not JSONL
- tiddlywiki_ene_bridge.py: use canonical_json (ensure_ascii=False) to
  preserve non-ASCII hash stability
- ollama_deepseek_review_emitter.py: restore "sha256:" prefix wrapper
- md_to_jsonl_converter.py: restore "sha256:" prefix via compute_sha256
- text_container_to_jsonl.py: restore "sha256:" prefix via compute_sha256
- kotc_sim.py: restore "sha256:" prefix on sha256_text
- gccl_waveprobe.py: restore Q16_MIN/Q16_MAX clamping on q16_add/sub/mul
- vcn_famm_transport.py: restore Q16_MIN/Q16_MAX clamping on q16_add/sub/mul
- lib/jsonl.py: add canonical_json() with ensure_ascii=False
