jpmschweitzerandClaude Opus 4.8 f771c9ce4e fix(simulation): address believability-stack review — all findings processed
Stack review (Hoshe + Tyre) of T-1083+T-1082+T-1080. Every finding fixed or disposed:

- believability.rs sample_indices: replace the rejection-sampling loop (could stall
  when n ≈ take) with deterministic partial Fisher-Yates — O(n), guaranteed
  termination, distinct, sorted (Hoshe+Tyre).
- believability.rs drainage proxy: exclude water-body districts (all elev 0, no banks)
  and require both wet + dry voxels — they were passing vacuously and inflating the
  metric (Hoshe).
- believability.rs read_cities: log skipped malformed rows instead of dropping silently
  (Hoshe).
- voxel.rs: add the 3 WaterBody zones to all_families_no_panic_at_extreme_positions +
  fix the "7 families" comment (Hoshe).
- climate_constants.toml: bold warning that [moisture_gradient] is not loaded until
  T-1032 — tune ClimateConstants::default() (Tyre).
- Q-123: record the per-zone "water renders wet" threshold + the land-relative
  vegetation-present denominator as calibration items (Tyre + the open 7th criterion).
- T-1083 ticket: note the sampling-fix attribution (landed in the T-1082 commit).

Believability golden regenerated (sampler + drainage fixes moved the metrics).
clippy --all-targets -D warnings clean; 1580 lib tests + harness pass.
