feat: complete code formatting and linting compliance

Browse source 
- Fix all Rust clippy warnings with targeted #[allow] attributes for justified cases
- Implement server-side IMAP SEARCH keyword filtering in Go implementation
- Add graceful fallback from server-side to client-side filtering when IMAP server lacks SEARCH support
- Ensure both implementations use identical filtering logic for consistent results
- Complete comprehensive testing of filtering and attachment handling functionality
- Verify production readiness with proper linting standards for both Go and Rust
