Pull Request Overview

This PR fixes a dead code warning by placing the Message::from_tsgo_lint_diagnostic method behind the language_server feature flag. The method was only used in language server contexts but wasn't conditionally compiled, causing a warning when building without that feature.

• Moved imports for Message, PossibleFixes, and language server types behind the feature flag
• Added #[cfg(feature = "language_server")] attribute to the Message implementation
