/**
 * Does a bracketed-paste buffer look like a terminal's stand-in for an image
 * paste rather than genuine pasted text?
 *
 * Cmd+V on a clipboard image yields an *empty* buffer on macOS Terminal/iTerm2,
 * but several Linux terminals instead emit a filename, a `file://` URI, or the
 * raw image header alongside the paste. Those shapes — and only those — warrant
 * the (async, 30-100 ms) clipboard probe in app.tsx. Substantial text returns
 * `false` so it can be inserted synchronously, keeping the common paste path
 * instant instead of waiting on an osascript / xclip / wl-paste shell-out.
 *
 * False positives are harmless: a literal text paste of "photo.png" probes the
 * clipboard, finds no image, and falls through to the text path anyway.
