Stellar Client v2.0.0

# StellarClient v2.0.0 - The Performance & UI Overhaul
Welcome to the biggest update in StellarClient history! This version completely redesigns the launcher from the ground up to provide a stunning user experience, built-in Modrinth integration, and aggressive engine optimizations to give you the highest possible frame rates in Minecraft.
### Highlights & New Features

• Brand New Interface: A sleek, dark-themed, glassmorphism UI with a responsive tabbed layout (Mods, Shaders, Textures, Settings).
• In-Launcher Content Hub: Browse, search, and install Mods, Shaders, and Texture Packs directly from Modrinth without ever leaving the launcher!
• Smart Asset Syncing: The launcher now automatically handles dependencies and caches your downloaded files so you never download the same mod twice.
• Cancel Launch Support: Need to abort? The Launch button now turns into a "Cancel Launch" button that lets you instantly interrupt Java streaming and mod syncing.

### Aggressive Game Optimizations
We’ve rewritten the engine startup sequence to squeeze every last drop of performance out of your hardware:

• Aikar's JVM Flags: Automatically injects the highly optimized Aikar G1GC flags to eliminate micro-stutters and improve chunk generation.
• Dedicated GPU Forcing: The launcher forcefully modifies your Windows Registry to ensure Minecraft always uses your Dedicated High-Performance GPU instead of integrated graphics.
• Process Priority Override: The Java process is automatically elevated to "High Priority" in Windows to prevent background apps from stealing your CPU.
• Input Lag Reduction: Windows Fullscreen Optimizations are forcefully disabled at the registry level for javaw.exe to minimize mouse input lag.

### Advanced Settings Engine
You now have full control over the engine:

• Customizable JVM Args: Assign custom minimum/maximum RAM limits and pass your own JVM arguments.
• Custom Java Path: Point the launcher to a custom JRE installation (with automatic .exe validation).
• Display Configurations: Manually set your launch Resolution Width/Height and toggle Fullscreen mode directly from the launcher.
