+### Bug Fixes

+- **Hook output fields**: Added missing hook output fields to match the TypeScript SDK, including `reason`, `continue_`, `suppressOutput`, and `stopReason`. The `decision` field now properly supports both "approve" and "block" values. Added `AsyncHookJSONOutput` type for deferred hook execution and proper typing for `hookSpecificOutput` with discriminated unions
