Subject: [PATCH] Fix unhandled exception in crash handler on macOS

This commit addresses a critical issue where the application would crash
due to an UnauthorizedAccessException when attempting to create or write
to a log directory. This was particularly problematic on macOS where the
LocalApplicationData folder might return an inaccessible or invalid path
in some environments.

Changes:
- Modified Program.cs to print global exceptions to Console.Error
  immediately, providing visibility even if logging fails.
- Wrapped log file operations in Program.cs in a try-catch block to
  prevent secondary crashes.
- Implemented robust log directory resolution with a fallback to
  Path.GetTempPath() if LocalApplicationData is unavailable.
- Applied similar robustness improvements to MainWindow.LogException.
- Updated agg-sharp submodule to macos-fixes branch and initialized
  recursive submodules (glfw-net) to ensure successful build and
  macOS compatibility.
