refactor(discovery): enhance exception handling and logging context in FileProcessor

- Add `DiscoveryErrorCode` and `FileSystemErrorCode` to improve error classification in `DiscoveryException`.
- Integrate `LogContext` into `FileProcessor` warnings for enriched logging details.
- Simplify `Environment` variable handling by removing redundant condition checks.
