rsx-modloader/bridge/src/test/fakeclient/FakeMain.java

// Drives the fake client the way the game would, so the bridge can be tested
// end to end: bring the client up, hand the mods to the vendor loader, then tick.
//
// The mod jars are NOT loaded here - the agent finds them in build/testrun/mods
// and feeds them to ilxq one by one, exactly as it does in the game. The last
// one loaded is the only one whose getRunnableList() the vendor keeps, so the
// first two only work if the bridge really has a single shared drain.
//
// The HUD part mimics the one path that matters: the compass widget renders, and
// only while the HUD screen's gate is open. Toggling the gate is what the game's
// own hide key does, so the test can check the panel follows it.
