fix(app): Ctrl+V pastes images in chat input (amicode#365)

[Rchari1]

Fixes harmoniqs/amicode#365

The VS Code webview chat runs as a sandboxed cross-origin iframe where navigator.clipboard / clipboardData are empty — image data is only readable via the outer webview relay (chat_panel.ts → navigator.clipboard.read() → dataUrl).

PromptInput v1 (classic composer, default when newLayoutDesigns is off — the reporters config on 0.2.1) only wired platform.readClipboardImage (desktop/TUI native) and never the bridge, so an image-only clipboard on Ctrl/Cmd+V produced no files, no text, and no attachment.

Mirrors the already-shipped v2 fix:

• import readClipboardImageViaBridge alongside readClipboardViaBridge
• readClipboardImage: bridge first, then platform fallback (parity with prompt-input-v2.tsx:389)
• setClipboardImageHandler → addAttachments for the global Ctrl+V fallback (v2 pattern)

Closes harmoniqs/amicode#365
Base: local/amicode (amicode fork line)
Test: manual Ctrl+Cmd+V with image on Darwin arm64 in VS Code webview; + button unchanged; text paste unchanged.

Summary by CodeRabbit

• New Features

📝 Walkthrough

Walkthrough

The prompt input now reads clipboard images through the webview bridge before using the platform fallback. It also registers a global clipboard image handler that adds supplied files to prompt attachments and removes the handler during cleanup.

Wire clipboard image sources into prompt attachments packages/app/src/components/prompt-input.tsx	The prompt input reads images through the bridge, falls back to the platform clipboard, registers a global image handler, adds received files as attachments, and clears the handler during cleanup.
