jpmschweitzerandClaude Opus 4.8 fb47f144f8 fix(simulation): address PR #162 review (morphology geometry)

Hoshe + Tyre CHANGES REQUESTED (§8 laws + D-010 confirmed clean):

- FjordWall floor 4+grade -> ~12m violated D-239 §9 (<=8m). Cap to
  glacier_grade.clamp(2,4) = 4-8m (still widens with glaciation, in-spec);
  add fjord_wall_floor_width_in_spec test. (Hoshe #1)
- BraidedDelta circular-distance wrap was one-sided (edge threads invisible).
  Fix to true modular distance: d.rem_euclid(64).min(64-d). (Tyre #1)
- BraidedDelta thread centres used correlated bit-slices of one u8 -> threads
  could merge. Derive 3 centres via independent splitmix64 passes (distinct
  salts) so separation holds across all phase values. Remove dead *64/64. (Tyre #2, Hoshe #4)
- Add N/S basin-direction guard asserts to the gorge + 2 fjord cross-section
  tests (were passing by seed luck). (Hoshe #2)
- meander_reach_stronger_sinuosity test was a tautology (|| elev_q!=elev_q
  always true). Rewrite: same elev_q, only morphology_zone differs, assert
  wet-tile sets differ -> fails if MeanderReach regresses to AlluvialPlain. (Hoshe #3)
- Fix FjordWall moraine + DuneStrand comments. (Tyre #3/#4)
- Lead: fix manual RangeInclusive::contains in the new fjord test.

cargo test passes (1457 lib), clippy -D warnings clean, fmt clean.
