Clean up AI slop and fix hanzo-training compilation

- Remove INTEGRATION_STATUS.md (random summary file)
- Clean emojis and verbose comments from training scripts
- Fix hanzo-training lib.rs exports (evaluation module, init_logging)
- Fix duplicate LoggingConfig types between config.rs and logging.rs
- Add tracing-subscriber env-filter feature for proper logging init
- Add training scripts for zen-agentic-dataset with clean code
