Removes outdated prompt files

Removes the `Chat Prompt.txt`, `VSCode Agent/Prompt.txt`, `Warp.dev/Prompt.txt`, and `v0 Prompts and Tools/Prompt.txt` files.

These files likely contain outdated prompts or configurations that are no longer needed in the current project. Removing them helps to clean up the codebase and prevent potential confusion or conflicts.
