Remove special detection rules for icon, asset, and slot props

[nathanacurtis]

Problem

The plugin applies special detection rules for icons, assets, and slots that go beyond what Figma provides natively. Users expect the tool to use Figma's built-in features — instance swap properties and slot properties — rather than custom heuristics.

Solution

Remove the special detection rules for icon, asset, and slot props. Instead, rely on Figma's native instance swap and slot property features to identify these cases.

Acceptance criteria

• Icons, assets, and slots are detected via Figma's native instance swap and slot properties
• Special detection heuristics are removed
• Output remains correct for components that use native Figma property features
