feat: Implement lazy-loading assets and cinematic 3D text engine

[0xarchit]

Is your feature request related to a problem?

The current MSI installer size is significantly inflated by the inclusion of heavy cinematic video assets (~10MB+). Additionally, users have no lightweight alternative for the break visuals if they prefer a zero-download experience or are on restricted data.

Describe the solution you'd like

A transition to a lazy-load architecture and a high-fidelity text engine:

1. Lazy Loading: Move heavy assets (like default.webm) out of the MSI. Fetch them in the background on first run with robust retry logic and live progress feedback.
2. Cinematic 3D Text Engine: Implement a physically 'thick' 3D text system with full rotation (X, Y, Z), customizable neon glow, and adaptive coloring that reacts to the system theme.
3. UI/UX Overhaul: A responsive 16:9 Live Preview in settings to accurately reflect these effects before application.

Describe alternatives you've considered

1. Static Placeholders: Simple images (low visual impact).
2. WiX Bootstrapper: Smaller MSI but requires complex separate payload management.
