feat: 🔐 Jules02: Security hardening — dynamic secret masking (#969)

* feat: 🔐 Jules02: Security hardening — dynamic secret masking

- Implement dynamic secret discovery in SecretMaskingProcessor to automatically mask all SecretStr/SecretBytes fields.
- Enhance URL credential extraction to protect embedded passwords in connection strings (database, redis, etc).
- Refactor main.py to dynamically exclude sensitive fields from CLI output and audit snapshots.
- Add comprehensive tests for the new masking logic.

- Enhance URL credential extraction to protect embedded passwords in connection strings (database, redis, etc).
- Refactor main.py to dynamically exclude sensitive fields from CLI output and audit snapshots.
- Update SECURITY.md to reflect implemented hardening measures.
- Harmonize numpy version to 2.2.7 across all requirements to resolve CI dependency conflicts.
- Fix Ruff lint errors in log_config.py.
