feat(http): enhance path handling with safe string slicing

- Replace direct slicing (`&s[0..5]`) with safe methods (`get`) in `serve.rs` to avoid panics.
- Add UTF-8 safety checks for paths with non-ASCII characters.
- Improve error handling for invalid slices using `unwrap_or_default`.

This ensures robust path manipulation in dynamic routing scenarios.
