fix: address review feedback on lifecycle configuration
- Extract LIFECYCLE_TIMEOUT_MIN/MAX constants from schema, use everywhere instead of hardcoded 60/28800 values (review comment 2) - Rename validateLifecycleOptions → parseAndValidateLifecycleOptions to clarify intent; return parsed values instead of mutating input (comment 3) - Unify create/add option types to number | string for consistency (comment 4)
