Tracker: #3866

Tracker: #3866

The first visible build of hulken, the first step of Foundation #3569.

• sx build main.sx bundles sx-out/macos/Hulken.app (SDL3 window, Metal); a camera circles a test scene of a ruin, crates and a marker on checkered grass, with towers out in the fog.
• src/render: camera, mesh builder, fragment-stage constants, and the scene renderer — per-fragment sun with hemisphere ambient, exponential distance fog, mipmapped repeat-sampled ground texture.
• tests/first_scene_golden.sx pins the scene from a fixed orbit point against tests/pixels/first-scene-metal.png; tools/run_tests.sh runs every test.

Verification

• Built with sx af8455c3: sx build main.sx bundles the app; launched, it shows the scene in a resizable window.
• bash tools/run_tests.sh: 1 passed. Recolouring the marker box fails the golden (284 pixels past tolerance).

A macOS window shows the first lit, fogged 3D scene ... 3e10bffe9d

build.sx bundles sx-out/macos/Hulken.app with SDL3 and Metal. main.sx opens
the window, and a camera circles the test scene: a ruin, crates and a marker
on checkered grass, with towers out in the fog.

src/render holds the camera, the mesh builder, the fragment-stage constants
and the scene renderer: per-fragment sun and hemisphere ambient light,
exponential distance fog, and mipmapped, repeat-sampled ground texture.

tests/first_scene_golden.sx renders the scene windowless on Metal from a
fixed orbit point and compares it with tests/pixels/first-scene-metal.png;
tools/run_tests.sh runs every test.
