What does this PR do?

This fixes slow/unstable image paste behavior in the TUI on Windows. (Fixes #12547)

Context:

  • On my machine, screenshot paste in the TUI was inconsistent and often very slow.

Changes:

  1. packages/opencode/src/cli/cmd/tui/util/clipboard.ts

    • Reworked Windows image read path to:
      • save clipboard image to a temp PNG,
      • read it with Bun,
      • clean up locally with rmSync.
    • Added in-flight reuse for concurrent reads so repeated triggers don't spawn duplicate work.

  2. packages/opencode/src/cli/cmd/tui/component/prompt/index.tsx

    • Unified image paste handling via tryPasteClipboardImage(...).
    • On Windows, image probing is now applied consistently for:
      • paste key handling (Ctrl+V / Shift+Insert path),
      • onPaste flow before falling back to text.
    • Added a render refresh after image insertion to make the placeholder update reliable.

Why this works:

  • The temp-file path avoids fragile stdout/base64 transport from PowerShell.
  • Prompt-side flow now consistently prefers real clipboard image data over ambiguous pasted text payloads.

How did you verify your code works?

  • Verification on Windows:
    • Press screenshot key on your keyboard, Then copy it, Paste it in the TUI.
    • Screenshot clipboard image paste now goes through the same image path and inserts image parts in prompt
