feat: playback overlay with seek bar, auto-hide and double-tap skip (v0.3.4)

New PlaybackOverlay component replaces the old hint bar in ChannelScreen.
The overlay sits as a fullscreen layer above the app during playback:

- Auto-hides after 5 s while playing; stays visible when paused;
  reactivated by any gamepad key press or mouse movement
- Center play/pause button, channel avatar, title, LIVE badge
- VOD: seek bar with pointer-capture scrubbing, current time / total duration
- Live: pulsing LIVE indicator instead of seek bar
- Double-tap zones left/right (±10 s) with animated skip feedback
- Gamepad hints in the top bar
- New icons: PlayIcon, PauseIcon, StopIcon in Icons.tsx
- New IPC channel `playback:time-update` (~1 Hz) pushes absolute playback
  position from main process to renderer; adds PlaybackTimeUpdate type
  and onTimeUpdate bridge in preload + t4sd.d.ts
- PlaybackEvent extended with durationSeconds and isLive fields

-- **VAAPI Hardware-Decoding** -- GPU-beschleunigte Videowiedergabe auf dem Steam Deck
+- **Language-Filtered Streams** — Top streams filtered by German/English
+- **Account Screen** — User profile, app version, logout
+- **VOD History** — Local SQLite database with playback history and progress
+- **VAAPI Hardware Decoding** — GPU-accelerated video playback on Steam Deck
+- **Quit Dialog** — Confirm quit via Xbox/Start button

+  ├── Helix Client  -- Twitch API (followed channels, streams, VODs, categories, chapters via GQL)
+  ├── Playback      -- Streamlink (Live) / mpv (VODs) with IPC control

+  └── React UI      -- Screens: Login, Following, Browse, Category, Channel,
+                       StreamList (DE/EN), Settings, Account
+```
+
+## Installation (Steam Deck)
+
+```bash
+flatpak install --user twitch4steamdeck.flatpak
+flatpak run tv.twitch4steamdeck.App
+```
+
+Finished Flatpak bundles include everything (incl. mpv, Streamlink, and Twitch integration) — no further setup required.
+
+---
+
+## Build yourself (developers)
+
+### Prerequisites
+
+- [Node.js](https://nodejs.org/) >= 20
+- npm
+- For Flatpak build: WSL2 (Ubuntu) with `flatpak`, `flatpak-builder`, `librsvg2-bin`
+
+### Setup
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/<user>/twitch4steamdeck.git
+   cd twitch4steamdeck
+   ```
+
+2. Register your own Twitch app at https://dev.twitch.tv/console/apps:
+   - **OAuth Redirect URLs:** `http://localhost`
+   - **Client Type:** Public
+
+3. Create `.env`:
+   ```bash
+   cp .env.example .env
+   ```
+   Enter the Client ID from step 2 into `.env`:
+   ```
+   MAIN_VITE_TWITCH_CLIENT_ID=your_client_id_here
+   ```
+
+   > The Client ID is embedded into the app at build time. End users installing a finished Flatpak do not need to register their own Twitch app.
+
+4. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+### Development
+
+```bash
+npm run dev
+```
+
+Starts Electron with Hot-Reload (electron-vite).
+
+## Build
+
+### Desktop (AppImage)
+
+```bash
+npm run package
+```
+
+Creates a Linux AppImage under `dist/`.
+
+### Flatpak (Steam Deck)
+
+The Flatpak build must run in WSL2 on the Linux filesystem (not under `/mnt/`):
+
+```bash
+# Copy project to Linux filesystem
+cp -rp /mnt/c/Projekte/twitch4steamdeck ~/twitch4steamdeck
+cd ~/twitch4steamdeck
+
+# Run full build (incl. mpv, streamlink, Electron)
+bash flatpak/build-flatpak.sh
+```
+
+The script handles automatically:
+1. Install Flatpak runtimes (freedesktop SDK 24.08, Electron2 BaseApp)
+2. npm install + rebuild native modules (better-sqlite3 for Linux x64)
+3. electron-vite build
+4. Generate Streamlink Python deps
+5. Run flatpak-builder (builds mpv 0.41.0, libass, libplacebo, Lua 5.2)
+6. Create Flatpak bundle and transfer via SCP to Steam Deck
+
+## Gamepad Layout
+
+| Button | Function |
+|--------|----------|
+| A | Confirm / Select / Play-Pause |
+| B | Back |
+| D-Pad / Left Stick | Navigation |
+| LB / RB | Switch tabs |
+| L2 | Rewind (VODs) |
+| R2 | Fast forward (VODs) |
+| Xbox / Start | Quit dialog |
+
+## Security
+
+- **Twitch tokens** are stored encrypted in the OS keystore (Electron `safeStorage`) and never end up in the build or repository
+- **Client ID** is a public identifier (Public App) and not a secret
+- `.env`, `out/`, `dist/` and `userData/` are excluded in `.gitignore`
