Normalize 'GIF' -> 'Gif' in docs
Standardize capitalization of the GIF token to 'Gif' across documentation for consistency and readability. Applied changes in Cache-Management.md, Create-Property-Listener-Filters.md, Create-Web-Architecture.md, FAQ.md, and Troubleshooting-Common.md. Also adjusted a minor list formatting in Create-Property-Listener-Filters.md.
Add VlcPlayer to engine documentation
Add VlcPlayer references across docs to reflect its support as an alternative media engine. Updates include audio/API notes, JS bridge availability, Engines Overview, Library customize menu, Property service cache path, Runtime Dependencies (non-mpv alternatives), Settings engine lists for Gif/Video, Troubleshooting, and GIF type documentation. These changes align documentation with VlcPlayer being a valid engine for GIF and Video playback and clarify where audio/system data is not available.
Add VlcPlayer engine and update docs/enums
Introduce the new VlcPlayer live engine: add Engine-VlcPlayer.md and wire VlcPlayer into documentation, enums, settings, caches, logs, publish pipeline, preprocessor symbols, properties, and runtime-dependency pages. Update references/counts from seven→eight engines, include VlcPlayer in EngineType/PropertiesType lists, allowed-engine matrices (Gif/Video), cache and AppData paths, customization/property-panel docs, and publish scripts/docs to include the new project. Documentation clarifies libVLC is bundled (no runtime prompt) and notes hardware-acceleration behavior and GIF handling. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
