## Message

```
gpui_web: Implement clipboard write and paste (#60890)

# Objective

write_to_clipboard was a no-op and read_from_clipboard returned None.

## Solution

Writes go through the browser's asynchronous Clipboard API,
fire-and-forget, invoked synchronously inside the user's input event so
the user-activation requirement holds.

Reads cannot be implemented the same way: the async clipboard read API
cannot fit read_from_clipboard's synchronous signature. Paste is instead
delivered by a DOM paste listener on the hidden input, whose
ClipboardEvent exposes clipboardData synchronously; the text feeds the
active input handler. This covers keyboard-, menu-bar- and
context-menu-initiated paste. Note the keyboard path requires the paste
chord's keydown to reach the browser unconsumed (apps should not bind
cmd/ctrl-v on web).
