pub fn run_default() -> Result<()>Expand description
Boots a Khora game with the default runtime app: auto-detects pack vs
loose assets, registers every default decoder, and loads the scene
named in runtime.json. This is what the pre-built khora-runtime
binary calls and what a user project’s src/main.rs should call when
it doesn’t need to register custom components/agents/lanes.
Returns Err only on irrecoverable startup failures (no assets at
all, missing exe path). Per-frame errors are logged and the loop
continues.
