tool: pin ruff version

[willcl-ark]

Hopefully this will fix the ruff inconsistencies between local and CI envs.

Install the correct version using uv:

# install
$ uv tool install ruff@0.6.8

# use
$ uvx ruff@0.6.8 check .

If this is the only version you have installed then it may be possible to still use the shorthand, if the version comes back correct:

$ uvx ruff --version
ruff 0.6.8

$ uvx ruff check.

--> uv tool install ruff@0.6.8
error: Failed to parse: `ruff@0.6.8`
  Caused by: Expected path (`/Users/matthewzipkin/0.6.8`) to end in a supported file extension: `.whl`, `.zip`, `.tar.gz`, `.tar.bz2`, `.tar.xz`, or `.tar.zst`
ruff@0.6.8
     ^^^^^

I do like this:

(.venv) --> uvx ruff check .
ruff failed
  Cause: Required version `==0.6.8` does not match the running version `0.6.9`

[pinheadmz]

ok the command that worked for me was uvx install tool 'ruff==0.6.8'
