Fix runtime evidence collection and improve DXVK diagnostics

- Expanded DXVK evidence patterns in `wine_capture.rs` to include `info: Game:`, `D3D11InternalCreateDevice`, and swapchain/Vulkan startup logs.
- Implemented a retry mechanism with short delays in `pipeline.rs` to handle asynchronous Wine log flushing.
- Improved diagnostics for empty logs by distinguishing between early scans of active processes and exited processes.
- Refined WineD3D fallback detection to prevent false positives when DXVK/VKD3D are confirmed.
- Added regression tests for symlink deployment and new evidence patterns.
