Vyper Compiler updates needed

[ryestew]

• [ ] Patrick error report: This contract won't compile:

  
  # I'm a comment!

SPDX-License-Identifier: MIT

pragma version 0.4.0

my_favorite_number: uint256

gives this errror
<img width="273" alt="image" src="https://github.com/user-attachments/assets/1c225b3a-6e13-4aca-bae1-032339db9678">

this looks like the Vyper plugin is not parsing the error message correctly.

Also try with:

pragma version 0.4.0
For some reason, it only works with:
pragma version ^0.4.0

and 
- [ ] Toaster needs updating - when you clone the vyper examples repo - it says in the toaster - snekmate
