fix(hooks): find console.log in modified files from a subdirectory session

check-console-log took the paths from `git diff --name-only HEAD`, which are relative to the repository root, and checked them with fs.existsSync from the hook's working directory. In a session started in a subdirectory, such as a monorepo package, no path existed from there, so the hook never warned. Resolve each path from the repository root. The exclusion patterns and the warning still use the root-relative path.
