Plasmoid Visualizer v1.4 - Persistence & Polish

This update brings the standalone application to a "production-ready" state with standardized configuration, a playlist system, and refined visual isolation.

Configuration & Persistence

• TOML Settings: Transitioned to a robust TOML-based configuration backend using toml++.
• XDG Compliance: Settings are now saved to ~/.config/PlasmoidVisualizerStd/config.toml (Linux standard).
• Auto-Save/Load: Your layers, colors, and folder paths are automatically restored on startup.
• Commit Reference: d2badfc

Playlist & Library

• Music Folder Scanning: Added a dedicated Playlist window that scans folders for .mp3, .wav, .flac, and .ogg files.
• Instant Playback: Quick-select songs from your collection with automatic "File Mode" switching.
• Commit Reference: d2badfc

Visual Refinement & FBO Isolation

• FBO Persistence: Visualizer effects (Glow, Bloom, Phosphor Decay) are now isolated in a Framebuffer Object.
• Ghosting Fix: UI windows no longer "bake" into the background trace—they stay crisp and clean.
• Analog Graticule: Added a 10x10 graticule grid for the Oscilloscope XY mode with proper aspect ratio centering.
• Quad Shader Dimmer: Modernized the phosphor decay pass to use a dedicated quad shader for better performance and compatibility.
• Trace Thickness: Added a dedicated slider to adjust the physical width of the sweep line for all line-based visualizers.
• Commit Reference: c263050, 5425d19
