[FEAT] prompt users when they save a file that’s going to kick off a full compile, “this will run a full compile, are you sure?”

**Is your feature request related to a problem? Please describe.**

When a user saves a file that requires kicking off a full compile (ex: dbt_project.yml) _and_ that full compile takes a significant amount of time (in some cases 5+ minutes), they enter into a blocked state while that full compile is running.

Users don't know that "saving the dbt_project.yml" == "kicking off full compile" == "blocked for 5 minutes".

We should prompt users when they save a file that’s going to kick off a full compile, “this will run a full compile, are you sure?”
- ideally, only if a full compile will take more than 5/10 seconds

Additionally, we should indicate that static analysis for models is blocked while that full compile is happening (covered [here](https://github.com/dbt-labs/dbt-core/issues/13731)).
