Gahow Wang 2a92f268a9 docs: fill the Phase 19 gap, refresh README/roadmap to actual state ...

- docs/19-gpt-oss-moe.md: the numbered series jumped 18->20; write up
  gpt-oss arch deltas, harmony pitfalls, and the two CUDA debugging
  postmortems (fully-masked-tile NaN in flash-attention sinks;
  pre-__syncthreads early return reading uninitialized smem in the
  decode GEMV) — the highest-value learning content of that phase.
- README: models/perf/capabilities were frozen at the Qwen3-only era;
  now lists gpt-oss MoE, TP/PP, FP8/MXFP4, sparse MoE, and the
  llama.cpp standing.
- Roadmap: record where reality diverged from the plan at Phase 18+,
  add milestone entries and the ranked next-phase candidates
  (21 CUDA-graph MoE decode, 22 non-expert quant, 23 sparse prefill).
- sparse-moe benchmark doc: post-review-fix numbers.
