/**
 * Native attachment-picker smoke test.
 *
 * Bug this regresses against:
 *   On macOS 26 Tahoe (ARM + Intel), the `rfd` 0.16 + objc2-app-kit 0.3.2
 *   binding for `+[NSOpenPanel openPanel]` asserts a non-nullable return.
 *   Tahoe started returning nil under some activation states, and the
 *   `none_fail` retain assertion panicked Rust, which `panic = "abort"`
 *   turned into a SIGABRT that took the entire app down — see commit
 *   `ca64da0` and the docs/cross-platform-webview-gotchas.md notes on
 *   `pick_files_macos`.
 *
 * What this spec verifies:
 *   Click the Add Attachment button in the compose modal. If the click
 *   crashes the underlying webview process (the previous Tahoe bug class),
 *   every subsequent webdriver call throws and the test fails. If the
 *   native picker opens, we dismiss it with Escape and assert the compose
 *   modal is still alive. Specifically catches the
 *   pick_files_macos → NSOpenPanel return path.
 *
 * Platform scope:
 *   Runs on every OS in the matrix. The crash class is macOS-specific, but
 *   on Windows/Linux this exercises the corresponding native picker path
 *   and is a useful smoke check there too.
