The CustomTitleBar (32px) was consuming vertical space in the 60px mini-player, pushing the play/pause button off screen. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Queue restore now only updates track info display without setting the Pause icon, since no playback is active at startup. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Integrates SMTC (System Media Transport Controls) to detect and control all active system media sessions. Includes per-session cards with thumbnail, metadata, timeline scrubbing, and playback controls. Also optimizes spectrum analyzer to use sliding window cache instead of full decode, and refactors SMTC artwork update. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Caution Review failedPull request was closed or merged during review 📝 WalkthroughWalkthroughThis pull request introduces three major features to Audiomatic: a spectrum-based audio visualizer with configurable frame rates, a system media session control panel for monitoring active media playback, and an inline metadata editor for track tags and artwork. Supporting changes include a mini-player ultra-compact display mode, animated view transitions, enhanced album art handling, and new services for spectrum analysis, metadata writing, and media session management.

1. Media timer keeps running 🐞 Bug ➹ Performance
When the window is hidden to tray, SuspendTimers stops only the player position timer and spectrum timer, leaving the MediaControl 1s tick timer running. Additionally, when sessions drop to zero, RebuildMediaSessionList clears panels but never calls UpdateMediaTimer, so an already-running media timer may never stop.
Agent Prompt
### Issue description
The Media Control timeline tick (`_mediaTickTimer`) is not suspended when the window is hidden to tray, and it may keep running even after sessions drop to zero because `RebuildMediaSessionList()` doesn’t call `UpdateMediaTimer()`.
### Issue Context
- `_mediaTickTimer` is created/started in `UpdateMediaTimer()`.
- `SuspendTimers()`/`ResumeTimers()` currently only manage `_player` position timer and `_spectrumTimer`.
- `RebuildMediaSessionList()` clears `_mediaSessionPanels`, which should cause `needsTimer` to become false, but the stop logic only runs if `UpdateMediaTimer()` is called.
### Fix Focus Areas
- Audiomatic/MainWindow.xaml.cs[1643-1699]
- Audiomatic/MainWindow.xaml.cs[1701-1719]
- Audiomatic/MainWindow.xaml.cs[2643-2654]
### Implementation notes
- In `SuspendTimers()`: stop `_mediaTickTimer` (or call `UpdateMediaTimer()` after setting a flag like `_isVisible=false`).
- In `ResumeTimers()`: call `UpdateMediaTimer()` to restart if `_viewMode == MediaControl` and panels exist.
- At the end of `RebuildMediaSessionList()`: call `UpdateMediaTimer()` so the timer starts/stops based on the new panel count.

2. Metadata editor ui freeze 🐞 Bug ⛯ Reliability
BuildMetadataEditorContent blocks the UI thread by calling writer.StoreAsync().AsTask().Result while constructing the flyout, which can hang or severely stall the UI when embedded artwork is present. The method also doesn’t dispose the DataWriter/stream it creates for the preview.
Agent Prompt
### Issue description
The metadata editor flyout content builder synchronously blocks on `writer.StoreAsync().AsTask().Result` while on the UI thread, which can freeze the app when opening the editor for tracks with embedded artwork.
### Issue Context
`BuildMetadataEditorContent()` is called directly from a context-menu button click and constructs UI elements synchronously. It should not perform blocking waits.
### Fix Focus Areas
- Audiomatic/MainWindow.xaml.cs[1352-1377]
### Implementation notes
- Replace the synchronous wait with an async flow. Two viable approaches:
1) Defer the artwork preview load:
- Build the panel with placeholder initially.
- Kick off an async method like `LoadArtworkPreviewAsync(track.Path, artPreview, artPlaceholder)` that `await`s `writer.StoreAsync()` and then updates the UI via `DispatcherQueue.TryEnqueue`.
2) Avoid DataWriter/StoreAsync entirely for preview by using an alternative that doesn’t require blocking (still must remain non-blocking on UI).
- Dispose/close the `DataWriter` and stream (`using`/`await using` where applicable) after `BitmapImage.SetSource`.
