Support pasting screenshots/images directly into Codex CLI

What feature would you like to see?

Codex CLI feature request: support pasting screenshots/images directly into an interactive
terminal session.

Current behavior:
Codex CLI supports image input via -i/--image file paths, but users need to save clipboard
screenshots to a file first.

Requested behavior:
Allow users to paste a screenshot/image from the clipboard directly into an active Codex
CLI prompt, similar to Claude Code.

Why it matters:
Screenshot-to-agent is a very common debugging and UI workflow. Requiring users to save a
file and pass -i interrupts the flow and makes the CLI feel worse for visual debugging.

Example desired flow:

1. Take a screenshot to clipboard.
2. Paste directly into an active codex CLI session.
3. Ask: "Fix this UI issue based on the screenshot."
