WHY IT NEEDS A POLICY

Why update_plan_proposal needs a policy

This tool creates or modifies data (plan proposal metadata) in a reversible manner without deleting or destroying information. It falls clearly into the Write category rather than Read (it modifies, not retrieves), Execute (it updates structured data, not arbitrary code/operations), or Destructive (changes are reversible via subsequent updates).

From the tool's definition Tool description states 'Update a plan proposal' with modifiable fields (title, description, status, tags, planIds). The action is a reversible modification of existing data.
