Parse more forms of apply_patch

What version of the VS Code extension are you using?

0.4.14

Which IDE are you using?

VS Code

What platform is your computer?

MacOS Sequoia 15.6.1 | Darwin 24.6.0 arm64 arm

What steps can reproduce the bug?

Select gpt-5-codex under model selection and ask for any change in the code

What is the expected behavior?

It should behave like gpt-5 and edit the files in the chat so I can see and undo the changes.

What do you see instead?

It only uses shell commands like
zsh -lc ls to list files
zsh -lc 'cat filename' to read files
zsh -lc 'apply_patch <<'"'"'PATCH'"'"'
* Begin Patch
* Update File: filename

Additional information

I'm still using the extension with gpt-5 model instead of gpt-5-codex because of this behavior.
Is this a bug or it's supposed to work like that?
