Omera v0.4.5

Fixed

• Windows setup now requires Visual C++ 2019 x64 14.29.30157.0 instead of
  inheriting the build machine's newer runtime version. Compatible existing
  installations can continue without an unnecessary runtime upgrade. The floor
  is verified against the required CRT imports and a native ONNX CPU inference
  fixture using the baseline DLLs.
• Runtime checks search both registry views and verify the four required native
  system DLLs. Setup explains missing or outdated files with their detected
  versions and links directly to Microsoft's official x64 redistributable.

Added

• Windows EXE setup defaults to the system language and lets users select English,
  Simplified Chinese, Traditional Chinese, Japanese, German, French or Spanish.
  Runtime guidance and language-selection text are localized. Silent and passive
  update installations remain free of language-selection dialogs.

Release testing

Automated regressions, native runtime compatibility and actual Windows installer
compilation are checked separately from installed-update acceptance. The owner
authorized this patch release; further Windows Sandbox testing remains deferred.
The complete Windows x64, macOS Apple Silicon and Linux x64 installed-update
matrix remains pending (#256).
