jpmschweitzerandClaude Opus 4.7	cabdd7c097	refactor(tooling): bump planet sim to native 1024×512, drop compute_rivers (#963 ) - planet_simulation: GRID 512×256 → 1024×512. The elevation noise is resolution-independent (normalized coords + absolute freqs), so the finer grid samples the SAME terrain — features keep physical size, generation stays deterministic. Pixel-unit constants (gaussian sigma, crater radii, peak-filter window, erosion slope) scale by GRID_W/512. Validated: non-Sol bodies render same-world-crisper at 1024. - Remove compute_rivers + _rivers_to_grid + the rivers/river_grid terrain keys: rivers are the Rust cascade's job (D8 drainage, D-208), the single source of river truth. The old heuristic didn't even reach the sea. - render_heightmap: stop painting rivers onto the relief (cascade/Atlas overlay computed rivers instead).

refactor(tooling): bump planet sim to native 1024×512, drop compute_rivers (#963 )

- planet_simulation: GRID 512×256 → 1024×512. The elevation noise is
  resolution-independent (normalized coords + absolute freqs), so the
  finer grid samples the SAME terrain — features keep physical size,
  generation stays deterministic. Pixel-unit constants (gaussian sigma,
  crater radii, peak-filter window, erosion slope) scale by GRID_W/512.
  Validated: non-Sol bodies render same-world-crisper at 1024.
- Remove compute_rivers + _rivers_to_grid + the rivers/river_grid terrain
  keys: rivers are the Rust cascade's job (D8 drainage, D-208), the single
  source of river truth. The old heuristic didn't even reach the sea.
- render_heightmap: stop painting rivers onto the relief (cascade/Atlas
  overlay computed rivers instead).

fix(assets): drop atomic writes, fix heightmap-size flag, default to 1024x512

The atomic .tmp→rename pattern caused silent FileNotFoundError on some
bodies. Removed in favour of direct writes — resume logic already handles
interrupted runs. Fixed --heightmap-size CLI flag which was silently
ignored due to Python default parameter binding. Changed default heightmap
resolution from 4096x2048 to 1024x512 (native simulation grid — no
information gain from upscaling).

feat(assets): planet generator pipeline — heightmap + globe from wiki data

Full terrain-to-render pipeline at tooling/planet-gen/:
- body_definition_parser: reads system index.md → body definitions
- planet_simulation: FBM + Voronoi ridges, Whittaker biome classification,
  D8 river routing, physics-driven craters (atmo × tectonics scaling)
- render_heightmap: 4096×2048 cartographic maps with hillshade
- planet_renderer: 512×512 globe with terrain UV mapping, clouds, rings
- biomes.toml: externalized color/classification tables (single source)
- scaffold_bodies: creates per-body index.md with YAML frontmatter
- batch: unattended processing with error handling, resume, determinism check

Supports all body types: temperate, arid, frozen, volcanic, barren,
oceanic, gas giant (banded + ringed), and moons (half-size, grey, cratered).
