Initial commit: SpaceshipTest, a top-down space RTS in Godot 4.7.1

Browse source 
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.

#!/data/data/com.termux/files/usr/bin/bash
# Renders a real screenshot of a Godot scene from Termux, via the Godot
# 4.7.1 Linux arm64 build inside the proot-distro Ubuntu container, using
# Xvfb (virtual display) + Mesa's softpipe software rasterizer.
#
# NOTE: Mesa's default software rasterizer, llvmpipe, crashes with
# SIGILL in this environment (confirmed via feasibility spike - its LLVM
# JIT appears to emit a CPU instruction this ARM64/proot/Android setup
# doesn't actually support, reproduced even with an empty project and no
# script). softpipe is Mesa's older non-JIT (pure C) rasterizer - slower,
# but doesn't hit this crash. Good enough for one-shot screenshots.
#
# Usage: bash tests/screenshot.sh <scene_res_path> <output_png_path> [wait_frames] [WxH]
# Example: bash tests/screenshot.sh res://Main.tscn /tmp/out.png 60 720x1280
#
# The resolution matters for anything with UI in it: the game is authored
# for a 720x1280 portrait viewport, so rendering at the default landscape
# size stretches the layout and makes it useless for judging whether
# controls fit. Pass 720x1280 when checking UI.
