FWIW the process I have used for large tasks with LLM programming looks like:
1) Use Cursor. It behaves far less quirky than VS Code for programming in my experience.
2) Explain what I want in detail, and ask it to create a high level plan file.
3) Then ask it to break the plan into more detailed subplans, and address any gaps until it is "confident" in the plans, and to save those plan files in the repo, so the work can be deferred to later. Repeat until it says it is confident.
