Add tool for getting project details

[b-per]

Summary

Add a new admin tool for getting dbt project details.
This can be useful for agents who want to know more about specific failing job runs.

For example, the flow could be

1. admin-tool-call: get the failing runs
2. admin-tool-call:get the information about the project (incl. the repo)
3. check in the repo if anything was changed recently (and clone it if required)
4. create PR in the repo with the fix
