chore: release v0.1.8

lib, linalg, ma, polynomial, fft, ctypeslib, matrixlib are imported
unconditionally by numpy/__init__.py and must not be trimmed.

 ### Bug Fixes
-- Prevent dialog `showModal` from auto-focusing first input ([db777fa](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/db777fa))
+
+- Fix numpy failing to import in the Windows installer — preserve required numpy submodules (`lib`, `linalg`, `ma`, `polynomial`, `fft`, `ctypeslib`, `matrixlib`) during build cleanup ([68614c9](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/68614c9))
+- Fix numpy failing to locate `libopenblas` DLL in the Windows installer — generate `_distributor_init_local.py` at build time and call `os.add_dll_directory()` at runtime ([456eb3a](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/456eb3a))
+- Fix visualizer toggle button not reflecting actual availability after audio device load ([ee51849](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/ee51849))
+- Fix visualizer WebSocket re-subscription firing before availability is confirmed from the API — moved from `connectWebSocket` to `loadAudioDevices` ([ee51849](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/ee51849))
+
+---
+
+### Development / Internal
+
+#### CI/Build
+- Generate `numpy/_distributor_init_local.py` in Windows build script to fix DLL loading in embedded Python ([456eb3a](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/456eb3a))
+
+#### Other
+- Broaden audio library import errors from `ImportError` to `Exception` and log at `warning` level with error details ([ee51849](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/ee51849))
