Brennan Benson 0c812843ef feat(native-chat): show a drop target on the whole chat pane (#20561)
* feat(native-chat): show a drop target on the whole chat pane

Dropping a file into a chat only worked if you hit the input box, and nothing
on screen said so. A drag aimed at the transcript fell through to the terminal
behind the chat, which pastes the paths into the hidden TUI.

The chat pane shell is now the drop surface. While a drag carrying files is
over it, the pane dims behind a card naming what the drop will do; the
composer's existing attach logic — workspace, execution-host and SSH-owner
checks included — runs unchanged from the wider element.

Two routes reach the composer and they are widened differently:

- an in-app drag is claimed in the renderer, so the pane calls the composer's
  handlers through a claim the composer publishes to the surface around it.
- an OS drag is delivered by the preload drop route, which consumes the event
  at `document` before React sees it. The pane widens that route by publishing
  the composer's scope key as the nearest drop marker, and learns the drag
  ended from a document-level listener rather than a React drop.

The surface lives in the chat portal because that is the one place wrapping
both the bridge and structured panes, so neither pane root grows a second copy
of this wiring.

No composer mounted (a question card owns the input region) means no marker and
no overlay, so that drag stays the terminal's. A guarded composer still answers
for the drag — that refusal is what keeps it out of the terminal — but the pane
does not invite a drop it will refuse.

* Fix native chat drop ownership across session surfaces

* Keep native drop completion listeners ready before hover renders
