Subject: [PATCH 60/71] feat(macos): drag & drop files and text into the
 terminal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Register the view as a drag destination for file and string pasteboard
types. A file drop pastes each path shell-quoted and space-separated (so
`program <drop>` works with spaces/metacharacters); a text drop pastes the
text verbatim. Both go through the existing bridge_paste path, so a running
program or the shell sees the input exactly as a normal paste — no engine or
input-path changes, fully isolated from the mouse/selection code.

Uses only 10.0-era pasteboard types (NSFilenamesPboardType/NSStringPboardType)
and a classic index loop (no fast enumeration), so it compiles on the gcc-4.2
ObjC frontend.
