Discussed in #6668 specifically this comment from @zackangelo:
> The biggest thing keeping me from using Zed as a daily driver is error
indication in the project panel. When I'm making big project-wide
changes I can't clearly see which files have errors (in editors like
VSCode the filenames turn red).
> VSCode seems to use a letter on the right gutter to indicate git
status and a number next to it to indicate diagnostic status. The color
indicates either.
This PR implements that, I added an opt-in `diagnostic_badges` setting
(default is false) that shows error and warning counts as colored labels
on the right side of each project panel entry. Counts bubble up to
parent directories.
When `diagnostic_badges` is enabled, diagnostic severity takes priority
over git status for entry text color.
Since warnings and git-modified share the same yellow, git status with
this option on is readable through the file icon decoration and the
absence of a number badge on the right.
Example:

/>
<img width="884" height="580" alt="image"
src="https://github.com/user-attachments/assets/198e9a45-dacd-4f1e-a66c-f2b84fd4db63"
/>
Release Notes:
- Added diagnostic count badges to the project panel, displaying error
and warning counts next to file names. You can modify this setting using
the `diagnostic_badges` option, which is enabled by default.
