Add stan setting to output static analysis report

[shivaraj-bh]

Generating this report is just:

# Inside haskellProjects.<project-name>
{
  settings.<package-name>.stan = true;
}

I'd also make one of the tests use this setting so stan is run as part of CI.

From the test logs:

And the HTML report is in the $out:

A bit of hardcoding here. I guess we could eliminate this by making the stan setting a submodule (providing an option to configure custom configuration path) instead of just a boolean, but I doubt that’s necessary.

I followed these instructions and added .stan.toml to the root:

juspay/vira@53a42bf

However, it doesn't seem to be used, because the generated report still doesn't exclude the StrictData suggestion:

It'd be good to demonstrate this in a sample repo, like https://github.com/srid/haskell-template - along with .stan.toml.

@shivaraj-bh Do we also use the HLS integration?

haskell/haskell-language-server#2908

Trying this on vira project I hit kowainik/stan#392 ... I wonder if this happens on internal projects too.

EDIT: Happens on haskell-template too: srid/haskell-template#147

Another thing worth considering: add a flake check that will fail if project health is not 100%. Poeple can always add excludes to their stan config if there's a good reason to reject certain suggestions.

No
