The inline "Generate post with AI" dialog never showed any output, even
after the queue job finished. Three independent issues stacked:
1. Event name mismatch in useAiStream. Listeners were CamelCased
(.TextDelta, .StreamEnd, .Error) but laravel/ai broadcasts events
with snake_case names via StreamEvent::type() (text_delta, stream_end,
error). Echo never matched, the listener never fired, status stuck on
'streaming' forever. Renamed to snake_case.
2. The streamer agent shares the structured-output prompt template with
PostContentGenerator, so the stream emits a JSON object like
{"content":"...","image_title":"...","image_keywords":[...]}, not
plain caption text. Added a previewText computed in AiGenerateDialog
that JSON.parse's the accumulated text and grabs .content. Mid-stream
the parse fails, so the preview stays empty (showing the existing
'...' placeholder) until stream_end produces a complete JSON.
3. The Generate button used v-if="status === 'idle'" — it disappeared
the instant generation started, leaving the user with no feedback.
Swapped to v-if="status === 'idle' || status === 'streaming'" and
used the Button component's built-in :loading prop so it stays
visible with a spinner inside while the agent runs.
