[Feature Request] Persistent Playback State: Auto-Resume last channel on App Launch/Boot

**Is your feature request related to a problem? Please describe.** Currently, the user experience is interrupted whenever the app is closed, the Android system kills the background process, or the device (Android TV/Smartphone) is rebooted. The user is forced to manually navigate through the UI (Categories -> Channel List -> Channel) to resume viewing, which is inefficient. **Describe the solution you'd like** I am proposing a **State Persistence** mechanism that saves the metadata of the currently playing stream to ensure continuity. 1. **Data Persistence:** The app should store the "Channel ID", "Stream URL", and "Category Name" in a local database or "SharedPreferences" every time a channel is successfully loaded. 2. **Lifecycle Handling:** - **On App Start:** The system should check for a "Last Played" entry. - **Auto-Execution:** If the feature is enabled, the app should bypass the main menu and initiate the player immediately using the stored parameters. 3. **Boot Integration:** Specifically for **Android TV**, the app should ideally have an option to "Launch on Boot" and immediately play the last channel, mimicking the "Instant-On" experience of traditional Cable TV hardware. **Detailed Functional Requirements** - **Connection Handshake:** The auto-resume should trigger only after the network state is confirmed as "Connected" to avoid immediate playback errors. - **Error Handling:** If the "Last Channel" fails to load (e.g., dead link or timeout), the app should gracefully fallback to the Home Screen with a brief notification (Toast). - **User Control (Settings Menu):** - **Resume Last Channel on Startup** (Toggle Switch) - **Startup Delay** (Selection: None, 2s, 5s) - To allow system processes/Wi-Fi to stabilize on slow devices. **Why this is important?** This feature is essential for **accessibility**, particularly for elderly users or those using Android TV boxes who expect a seamless, "plug-and-play" television experience without complex menu navigation.
