🧹 [Remove unnecessary allow(dead_code) in lexer]

[Tcode-Motion]

🎯 What: Removed the unnecessary #[allow(dead_code)] attribute from the LogosToken enum in compiler/lexer/src/lib.rs. Also removed the empty line left behind to prevent clippy::empty_line_after_outer_attr.

💡 Why: The attribute was masking the fact that the code is actively used (and generated correctly by logos-derive). Removing it improves accuracy and code health, keeping standard compiler checks intact to properly catch actual dead code in the future.

✅ Verification: Verified via cargo clippy --workspace --all-targets that the dead_code warnings don't actually trigger (meaning the code isn't dead). Also ran cargo test --workspace to ensure all functionality is preserved.

✨ Result: Improved codebase maintainability by keeping the compiler checks accurate and removing unneeded override attributes.
