Initial commit: SpaceshipTest, a top-down space RTS in Godot 4.7.1
A fleet of neon-outlined ships explores a procedurally generated, seeded infinite world: tap/joystick steering, pinch zoom, formation pivoting, planet landings, an ore economy with extractors and haulers, and player built structures (mothership, ship crafter, command centre). All art is hand-drawn with draw_* calls rather than textures, and the backgrounds are camera-relative shaders so they stay precise at large world coordinates. Includes a 35-test headless suite (tests/run_tests.sh) plus screenshot tooling that renders real frames through Xvfb and Mesa softpipe, since --headless has no GPU. Excluded from version control: .godot/ (import cache, and it holds export credentials), builds/, android/build/ and packaged APKs - all regenerable, and ~325 MB combined.
