Fix all CI/CD errors: clippy warnings and compilation errors

- Remove unused import std::path::Path from hooks.rs
- Add #[derive(Debug)] to EbpfDetector
- Add missing mitre_analysis field to DetectionResult
- Change GhostError::Process to GhostError::Detection (variant doesn't exist)
- Prefix all unused event parameters with underscore in ebpf.rs
- Fix formatting in hooks.rs

All tests passing (24 total). Clippy clean with -D warnings.
