WHAT IT DOES

What fizzy_unpin_card does on Fizzy Do MCP

WHY IT NEEDS A POLICY

Why fizzy_unpin_card needs a policy

Unpinning a card modifies its state (removes a pin attribute) but is a reversible action — the card can be pinned again. This falls under Write rather than Destructive since no data is deleted. Severity is low as the blast radius is minimal; it only affects the visibility/pinning status of a single card.
