Aura v1.0.8

What's Changed:

• Resident Whisper Server on CUDA: Introduced resident background server execution (whisper-server.exe) in src-tauri/src/whisper_runner.rs alongside Parakeet's resident server. When NVIDIA CUDA acceleration is active, the server keeps model weights (e.g. large-v3-turbo-q5_0) loaded directly in GPU VRAM (CUDA0), dropping transcription latency from ~15s cold starts down to ~250ms on discrete GPUs.
• Unified On-Demand CUDA Package Downloader: Extended download_gpu_binaries_inner in src-tauri/src/lib.rs to download, SHA-256 verify, and extract both the Sherpa-ONNX CUDA runtime (sherpa-onnx-v1.13.4-win-x64-cuda.tar.bz2) and Whisper cuBLAS runtime (whisper-cublas-11.8.0-bin-x64.zip containing ggml-cuda.dll) into %LOCALAPPDATA%\com.aura.app\binaries\cuda\bin\. This enables one-click GPU acceleration for both engines while keeping the base installer compact (~20–25 MB).
• Dynamic Working Directory DLL Routing: Configured start_whisper_server_unlocked and run_local_whisper in src-tauri/src/whisper_runner.rs to set their process working directory and PATH to %LOCALAPPDATA%\com.aura.app\binaries\cuda\bin\ when CUDA is selected. This allows ggml.dll's ggml_backend_load_all() to dynamically detect ggml-cuda.dll and initialize CUDA0 without requiring DLL copies to system directories.
• Model Verification Spinner & State Feedback: Added a dedicated status field to DownloadProgress in src-tauri/src/whisper_runner.rs and updated src/main.js to transition download cards into an animated installing state with a circular spinner during post-download SHA-256 integrity verification, eliminating the static 5–10s freeze at 100% on large model files.
• Native Neural Punctuation Transition: Removed legacy CT-Transformer external dependency and heuristic string manipulation (apply_voice_punctuation) in src-tauri/src/whisper_runner.rs in favor of native acoustic punctuation built into Whisper and Parakeet models, eliminating punctuation duplication and word trimming artifacts.
• Overlay Timer & Status Customization: Added the overlay_show_timer toggle in src-tauri/src/settings.rs and src/main.js, allowing users to hide duration counters and status labels from the floating overlay capsule while keeping the audio visualizer and critical error alerts intact.
• Full 9-Language Localization Parity: Synchronized and filled all translation keys across all 9 supported locales (ru, en, de, es, fr, it, zh, pt, tr) in src/main.js, strictly validated by automated tests in tests/frontend-static.test.mjs.
• Automated CI/CD Release Publishing: Updated .github/workflows/release.yml (releaseDraft: false) and configured osv-scanner.toml dependency filters to ensure production installer artifacts (.exe, .msi, .sig) build, sign, and publish automatically upon tag creation.
