Add SafetyProfile domain model with configurable safety constraints
(checkpoint, human approval, cost limits, retry limits, skill
categories, sandbox requirement). Integrate into Action model with
from_config/as_cli_dict support, and persist via LifecycleActionModel
safety_profile_json column.
Include resolve_safety_profile() stub that raises NotImplementedError
for local mode, signalling that real enforcement is deferred.
Add comprehensive test coverage:
- 20 BDD scenarios in features/safety_profile.feature
- 6 Robot Framework smoke tests
- 5 ASV benchmark suites (11 timing functions)
Add docs/reference/safety_profile.md reference documentation.
