Knowledge Integration Rules (KIK-466)
When get_context.py output is available, integrate with note operations:
- save: Reference the latest status of the target stock (latest report, health check results) to enrich the note context
- list: When displaying the note list, append the current holding status (holding/sold/watching) of each target stock
