Fix headless asset preprocessing hang

## Summary
- share custom RON asset loaders between the game and asset processor
- register image, font, and glTF loaders in the headless processor
- prevent `game_settings.ron` and `game.stylesheet.ron` from receiving ignored processed metadata

+## Production Build
+
+Production builds use the `production` Cargo profile and do not dynamically
+link Bevy or Rust. Development builds retain Bevy dynamic linking for faster
+iteration. Cargo stores the production profile under `target/production`,
+separate from development artifacts under `target/debug`.
+
+```sh
+cargo run --locked \
+  --bin process-assets --no-default-features --features debug_features
+cargo build --locked \
+  --profile production --no-default-features --features debug_features
+```
+
+The asset preprocessing command must be run from the repository root. It
+populates `imported_assets/Default`, which is then consumed by the production
+game without running the asset processor at startup.
