Previously the endpoint returned a single JSON object at the end. Apache+ PHP-FPM buffers the entire body until PHP exits, so a 160s azure_full run caused the browser to drop the fetch as "Failed to fetch" while the server was still synthesising — the response then arrived to a dead socket. Switch to application/x-ndjson with one event per line. The endpoint emits 'progress', 'start', 'step' (running/complete/warning/error), 'subq', and a final 'final' event carrying the full result payload. Output buffering is explicitly disabled so each line flushes through Apache as soon as the agent emits it. DbnDeepResearchAgent::run() now accepts an optional ?callable $emit and fires step:running before each step + step:complete after, plus a subq event per sub-question retrieval round. JS reads response.body as a stream, splits on newlines, updates the trace panel live, and renders the final result when the final event arrives. Status pill shows live progress detail (e.g. "Synthesising with Azure gpt-4o — this is the slowest step…"). Engine row in the form now shows expected duration per engine (~15-45s mini, ~60-180s full, ~30-90s GPU) so users know what they're in for before clicking Run.
