refactor: remove unused linter annotations

Remove unnecessary nolint directives that were previously used to
suppress linter warnings for unused code and magic numbers. These
annotations are no longer needed as the code has been properly
refactored.

Also renamed an unused parameter in handlerWorkspaceDidChange
Configuration to underscore to indicate it's intentionally unused.
