Pressing Esc to interrupt an agent turn now only returns the prompt to the chat input if the model has not yet started generating output; once a response has begun streaming, the prompt is left as-is.

Follow-up to #4544. That change returns an interrupted prompt to the chat input whenever the input is empty, but it does so even after the model has already begun producing a response. Returning the prompt at that point is confusing: the model already started (or finished) answering, so re-offering the text invites an accidental re-submission of an already-answered request.

This gates the restore on whether the turn has produced any output yet. execute_task_textual now notifies the app (via a new on_output_started adapter callback) the first time a turn emits streamed text or a tool call. DeepAgentsApp tracks this per turn in _active_turn_output_started (reset at the start of each send) and _restore_interrupted_message_to_input skips the restore once it is set. The empty-input guard and the Ctrl+C behavior are unchanged.

fix(code): skip Esc prompt-restore once output generation begins
57f4817 
Pressing Esc to interrupt a turn now only returns the prompt to the chat
input when the model has not yet begun generating output. Once streamed
text or a tool call has appeared, the prompt is treated as consumed so it
is not re-offered for a request the model already started answering.

Pressing `Esc` to interrupt an agent turn now only returns the prompt to
the chat input if the model has not yet started generating output; once
a response has begun streaming, the prompt is left as-is.

Follow-up to langchain-ai#4544. That change returns an interrupted prompt to the
chat input whenever the input is empty, but it does so even after the
model has already begun producing a response. Returning the prompt at
that point is confusing: the model already started (or finished)
answering, so re-offering the text invites an accidental re-submission
of an already-answered request.

This gates the restore on whether the turn has produced any output yet.
`execute_task_textual` now notifies the app (via a new
`on_output_started` adapter callback) the first time a turn emits
streamed text or a tool call. `DeepAgentsApp` tracks this per turn in
`_active_turn_output_started` (reset at the start of each send) and
`_restore_interrupted_message_to_input` skips the restore once it is
set. The empty-input guard and the Ctrl+C behavior are unchanged.
