Zed configurations in CMA

[piercefreeman]

Add a reasonable Zed project default for CMA.

pyrightconfig.json

Include the path to the venv, dependent on whether the project is using poetry or venv.

{
  "venv": "mylib-aXdKuegZ-py3.11",
  "venvPath": "/Users/{user}/Library/Caches/pypoetry/virtualenvs"
}

Default search flags

Exclude the auto-generated directories. Seems to already be the default behavior since zed-industries/zed#5443, where the search will ignore files in .gitignore. We already add our build artifacts to the template .gitignore so there's nothing else to do here.
