fix(simulation): orbital rung applies coast_warp_px — one coastline at every rung (T-1160)

The Global/Region rungs sampled the heightmap ocean mask raw while every
finer rung samples it at the coast-warped position — a structurally
different coastline at the orbital-to-district seam. Audited on all 267
real body heightmaps at region spacing, coastal band only: 5.01%
land/ocean classification disagreement (2,911 of 58,073 cells), mean
displacement ~6.0 km, max ~18.9 km. Fork taken: APPLY the warp —
derive_orbital_at_metres now runs invent_primitives' steps 1-3 (driver
climate -> coast character -> coast_warp_px) before sampling, still
skipping detail-scatter (its octave ceiling, 32.8 km, is below region
spacing; the WARP's octaves reach 262 km, which is why skipping it was
wrong). Cost measured: ~784 ns/cell added (~15 ms on an Earth-class
Global canvas; low hundreds of ms parallel at the 8.3M-cell ceiling).
The ignored audit test preserves the pre-fix baseline for the record.
Golden re-pinned — region rows only, district/quarter byte-identical.
project.yaml 0.4.2 -> 0.4.3: orbital canvas bytes changed, client disk
caches must miss. Awaiting Araminta's review-seat sign-off per ticket.
