"""Serve over Streamable HTTP with JSON responses (no SSE stream); HTTP-only, so this exports ``build_app()``.

The 2026-07-28 path is stateless and JSON-only by construction today; the
|
|
``json_response=True`` flag also forces JSON for the legacy (2025-era) branch on
|
|
the same endpoint. Mid-call notifications are dropped.
