Windows: Ctrl+V should auto-detect clipboard image instead of requiring Alt+V

Problem

On Windows, pasting an image from clipboard requires Alt+V, while Ctrl+V only pastes text. Most users don't know Alt+V exists, so they assume CLI image pasting is not supported.

Typical user experience:

1. Win+Shift+S to capture screenshot
2. Ctrl+V → nothing happens
3. User gives up

Suggestion

Make Ctrl+V detect clipboard content type automatically:

• Text → paste text
• Image → paste image

No conflict since text and image are mutually exclusive. macOS/Linux already uses Ctrl+V for both.

Why this matters

• Alt+V is not discoverable
• Makes a useful feature invisible to most Windows users
