 * POST-based SSE reading for the assistant chat stream. The browser

 * The framing parser is vendored here (rather than depending on an internal SDK)
 * so this module stays self-contained and consumable by any host. It mirrors the
 * standard SSE wire format: events separated by a blank line, `event:` / `data:`
 * fields, `:`-prefixed comments ignored, multi-line `data:` joined with `\n`, and
 * each event's data JSON-parsed (falling back to the raw string).
