### Decky Loader Plugin

The DeckyVault plugin is now available for Steam Deck! Record performance metrics directly from the Quick Access Menu and upload them to DeckyVault.

**How it works:**
1. Add `~/deckyvault-mangohud.sh %command%` to your game's Steam launch options
2. Launch the game and get to gameplay
3. Open the Quick Access Menu and press **Start Recording**
4. Play for a bit, then press **Stop Recording**
5. Export to a `.deckyvault.json` file or upload directly to DeckyVault

### Key Features

- **Auto game detection** — The plugin detects the currently running game and fills in the name and Steam App ID automatically
- **Proton version detection** — Reads the Proton version from Steam's config files
- **MangoHud integration** — Configures MangoHud for logging with `autostart_log`, `control=mangohud`, and `output_folder=/tmp`
- **Controller-friendly UI** — Built with `ButtonItem` and `TextField` from `@decky/ui` for full controller navigation
- **API key support** — Create API keys in your DeckyVault settings for direct upload from the plugin
- **Config export/import** — Save and load your plugin configuration from Downloads
- **Wrapper script** — Forces MangoHud to use the correct config file via `MANGOHUD_CONFIGFILE`

### API Key Authentication

Added API key support via Better Auth's API Key plugin. You can now:
- Create and manage API keys from your profile settings
- Use API keys for direct upload from the DeckyVault plugin
- API keys use the `dv_` prefix for easy identification
