Addresses two pieces of PR #1042 review feedback.
1. PassthroughComposer used to clear the textarea unconditionally after
onSubmit resolved, but the WS handler swallowed transport errors and
resolved normally — so a network blip silently wiped the user's typed
message with no way to retry. Add a passthrough-specific send handler
that rethrows after toasting, and gate the setValue("") in the composer
on success. Preserves the ACP handler's swallow-and-resolve contract
to avoid leaking unhandled rejections into the TaskChatPanel chain.
New regression test: "preserves the typed text when onSubmit rejects".
2. Add a one-line comment at the passthrough branch in Executor.Prompt
explaining why dispatchOnly is not forwarded — PTY writes are inherently
fire-and-forget, so the flag has no analogue.
