v4.0.1

[4.0.1]

Added

• Add default target support to target(...), allowing target("OperationName") to populate the generated setting initial expression, production Host setting, and graph edge once the named target item exists.
• Allow ComponentRef.connect(...) to accept class-declared target() descriptors, supporting static-friendly calls such as rest.connect(Rest.Output, operation).
• Add package typing metadata with py.typed and explicit ComponentRef return annotations for production factory methods.

Fixed

• Expose declared and manual target settings through dir(ComponentRef) so rest.my_target style graph handles are discoverable by runtime autocomplete.
• Validate target setting values that reference missing production items.
• Normalize setting(...) and target(...) descriptors used as production setting keys before validation and IRIS rendering.
• Improve component registration failures during migration with targeted guidance for missing IoP support classes and container startup races.
• Render generated instance-style Python routes with component.connect(...).
• Refactor business process and operation message dispatch around normalized message keys for @handler, typed methods, legacy DISPATCH, and native IRIS requests.
