P4 (WIP): GenCall-equivalent calling, BAF/LRR, sex, GTC v5, simurg genotype

- genotype/clusters.py: EGT aligned to manifest order (float32 mean R)
- genotype/gencall.py: flair, six-case likelihood, priors/posteriors,
  fuzzy sub-scores and score map, vectorised with the reference's
  float/double evaluation order and libm transcendentals
- genotype/baf_lrr.py, sex.py (rules v1/v2), sample.py (IDAT -> Gtc)
- pipeline/inputs.py shared by ingest and genotype
- pipeline/genotype.py + CLI: GTC per sample, sample_summary.tsv/json
  (OUT-060..063), run manifest
- GTCs from IDATs are byte-identical to the oracle for 36 GSA samples x
  2 normalization versions (NaN sign canonicalised to the x86 pattern)
