CLI does not identify Avalonia (.axaml) files

[lmejiauxd]

Describe the bug
When running XamlStyler through the console, there is no way to force it to handle .axaml files as Avalonia ones. As a result, it incorrectly escapes the child combinator (>) in style selectors as >

To Reproduce

1. Create an .axaml file containing a style selector with a child combinator (>).
2. Format the file with XamlStyler through the console.
3. The > character is replaced with >.

Expected behavior
XamlStyler should recognize .axaml files as Avalonia ones when run in the console, preventing incorrect character escaping in style selectors.

Version Info:

• OS: Windows 11 25H2
• Visual Studio: VS2026 (18.8.2)
• XAML Styler: Console (3.2501.8)

Additional context
XamlStyler correctly recognizes Avalonia files when run inside Visual Studio by using the EnvDTE.Document API, but that's not available in the console tool.
