Positron: Render on Save button applies at project level

[cwickham]

Bug description

Checking the "Render on Save" checkbox applies it to all documents in a project. That is, checking the box in one open file, checks it for any other files in the project.

It may be this is the desired behavior (i.e. it is equivalent to checking the setting Quarto > Render: Render on Save), however, it is not the default behavior in RStudio. In RStudio the checkbox with the same name behaves more like setting render-on-save in the document header:

---
editor:
  render-on-save: true
---

If the current behavior is indeed the desired behavior, this needs to be clarified in the docs on quarto.org, which I am happy to do.

Steps to reproduce

Create test-project

quarto create project default test-project test-project

In test-project/

touch other.qmd

Check box for "Render on Save" in other.qmd.

Actual behavior

Box for "Render on Save" is also now checked in test-project.qmd.

Expected behavior

Based on RStudio behavior, Box for "Render on Save" in test-project.qmd should remain unchecked.
