fix(tray): dynamically create/destroy tray icon on setting toggle

Previously, toggling the system tray in the settings updated the configuration but did not instantiate or destroy the tray immediately. This caused a desynchronization bug where the application could minimize to a non-existent tray, creating a ghost instance.

The `set-feature` IPC handler now intercepts the `systemTray` key to apply the state at runtime before persisting the config.

+# External binaries
+
+This project depends on three external tools that are **not bundled in the repository**.  
+You must download them manually and place each binary in the correct folder before building or running the app locally.
+
+---
+
+## Required tools
+
+| Tool    | Role                                        |
+|---------|---------------------------------------------|
+| yt-dlp  | Video and audio download engine             |
+| ffmpeg  | Media encoding, transcoding, muxing         |
+| ffprobe | Media file analysis and metadata extraction |
+| deno    | JavaScript / TypeScript runtime             |
+
+---
+
+## Folder structure
+
+Place the binaries exactly as shown below.  
+Do not rename them — the application resolves them by these exact names.
+
+```

+
+Each archive contains a single binary. Rename it to `deno` (or `deno.exe` on Windows).
+
+---
+
+## Permissions (Linux )
+
+After placing the binaries, make them executable:
+
+```bash
+chmod +x resources/binaries/linux/yt-dlp
+chmod +x resources/binaries/linux/ffmpeg
+chmod +x resources/binaries/linux/ffprobe
+chmod +x resources/binaries/linux/deno
+```
+
+---
+
+## Notes
+
+- These binaries are excluded from version control via `.gitignore`.
+- Always use the latest stable release of each tool.

+        <p>
+            Freedom Loader is a free and open-source graphical interface built
+            around yt-dlp, the powerful command-line media downloader. It lets
+            you download video and audio from hundreds of supported websites
+            without ever touching a terminal, with no ads, no tracking, and
+            no questionable third-party services.
+        </p>
+        <p>
+            Under the hood, Freedom Loader bundles yt-dlp and ffmpeg directly,
+            so there is nothing extra to install: paste a link, choose a
+            format and quality, and the app handles fetching, converting
+            and tagging the file for you.
+        </p>
+        <p>Features include:</p>
+        <ul>
+            <li>MP4 video or MP3 audio downloads with embedded metadata and thumbnails</li>
+            <li>Quality selection from best to specific resolutions (1080p, 720p, 480p)</li>
+            <li>Codec choice: H.264, H.265, AV1, VP9 and Theora</li>
+            <li>Playlist downloads with automatic per-playlist folders</li>
+            <li>Cookie-based access to age-restricted and member-only content</li>
+            <li>Custom theme system with a web-based theme creator</li>
+            <li>Real-time download progress with network speed indicator</li>
+            <li>Optional Discord Rich Presence integration</li>
