Issue for this PR
Closes #18622
Type of change
What does this PR do?
processMessagealso on user messages in the live path. This is so the updates seen on the "live" (prompt / command) path are the same to what is emitted when hitting/load(replay path) - which does emit these chunks for the user messagesNote
Opencode messageID are not UUID, so this is not strictly speaking compliant with the experimental ACP messageID standard.
I personally think that the standard should adapt to allow for ACP messageID to actually be the internal messageID stored and managed by the agent server - otherwise clients can't use it to interface directly with the server when needed (e.g. - revert)
How did you verify your code works?
Used the emitted messageIds to revert messages, and reconcile the same message between live (prompt) path and reload path.
