Pull Request Overview

This PR refactors the language server by extracting duplicated logic for generating inverted diagnostics into a reusable function. The refactoring moves the generate_inverted_diagnostics function to the error_with_position module and updates both TsgoLinter and IsolatedLintHandler to use this shared implementation.

Key changes:

Extracted duplicated inverted diagnostics generation logic into a shared function
Updated import statements to include the new generate_inverted_diagnostics function
Simplified diagnostic processing logic in both linter implementations
