fix(#690): validate config files before deploy

Wire config_validator.py into deploy.sh. Validation runs
before copying config.yaml to ~/.hermes/. Deploy aborts
with clear error if validation fails.

Acceptance criteria:
- Validates YAML syntax before writing
- Rejects deploy on validation failure with clear error
- Graceful skip if python3 not available
