`analyze_files` should filter results to the paths supplied.

Problem

If you have a LOT of analyzer errors, but the LLM supplies paths to analyze, the analyze_files tool currently returns ALL of the analyzer errors, regardless of the paths supplied. While this can help the LLM get a bigger picture of the problems, it can also eat up a lot of context really quickly with things that are irrelevant to the file it is working on.

For example:

The LSP only supports analyzing whole projects, so the analyze_files tool should filter the results so that it only includes files matching the paths supplied in the "paths" argument. Without a paths argument, it should return the entire set of results.
