What's Wrong?

Bug summary:

On Windows, the native UI mode fails with "requires git-bash" error
The claudeCode.environmentVariables setting with CLAUDE_CODE_GIT_BASH_PATH is ignored
Terminal mode works correctly with the same settings
The bash check happens before the extension reads the environment variables setting

What Should Happen?

Native UI mode should read claudeCode.environmentVariables before performing the bash check.
