Nearcade 3.0.4

This release focuses on quality-of-life improvements, fixing UI stutters, and handling larger game libraries more efficiently. We've also improved multi-instance routing and added a few updates for Steam Deck users.

Changes & Improvements

Core & Performance

• Background Game Scanning: Offloaded Steam game library detection (@nearcade/launcher-detect) to a background worker_thread with a 5-minute cache. This prevents the Node.js event loop from stalling for users with massive (1000+) Steam libraries.
• Audio Fallback Timeout: Re-enabled the Python OS-level audio fallback. If the browser fails to grab system audio, it will wait 3 seconds before automatically spinning up the Python audio driver.
• Smart Windows Setup: The boot script now checks for ViGEmBus.sys natively. If the driver is already installed, it silently skips the setup wizard and takes you straight to the dashboard.
• Version Parity: Synced the VPS router and package-lock.json up to 3.0.4.

Viewer UI & Extensions

• Identity Persist Extension Fix: Rewrote the Tampermonkey script's sync loop. It now uses a bidirectional memory cache, fixing a bug where visiting a new Zrok subdomain would wipe your saved viewer settings.
• Zero-Flicker Navigation: Fixed visual stutters on the dashboard splash screen and viewer UI. Custom chat colors and splash visibility are now applied synchronously before the DOM paints.
• Settings Modal & Controls: Moved viewer options into a new settings modal. Added a client-side stick deadzone slider so viewers can counter stick drift themselves, plus toggles for rumble and stream bandwidth.

Multi-Instance & Handhelds

• Dynamic Track Swapping: Moving a viewer to a different game instance on the Host Playground now swaps their WebRTC track on the fly without dropping the connection.
• Gamepad-Friendly Routing: Added an "Instance Assignment" dropdown to the roster cards so you can route players to games using just a controller (bypassing the need for drag-and-drop).
• Process Isolation: Inputs for viewers assigned to specific window instances are now strictly isolated to that game via bind-evdev.
• Steam Deck Updates: Added proper Steam Deck icon parsing for verified handheld users and fixed a requestAnimationFrame memory leak that was draining CPU when multiple controllers connected.

Bug Fixes

• Removed hardcoded scroll limits on the Host Playground URL list.
• Fixed teardown logic issues in stopCapture() during Multi-Instance mode.
• Dropped the fake StorageEvent from the Tampermonkey script that was crashing third-party extension dashboards.
