Stream a run of an authored agent
Stream a run of an authored agent — a preset over an agent’s run tool whose baked fields the agent honors.
The baked spec is read from the PresetManager in-memory map (the single
source of truth for every registered preset — versioning never gates
streamability). The request body supplies ONLY the remaining,
non-baked ToolInput fields; naming a baked field is a loud 400 rather than a
silent override. The baked fixed kwargs plus the request fields are combined at
the FIELD level, validated against the agent’s ToolInput, and mapped through
from_tool_input before astream — never a raw splat that would bypass
validation and the field mapping.

Path Parameters
Body
The input object for an agent run. Fields are agent-specific — validated at
runtime against the target agent's dynamic ToolInput model — so the request
body is a free-form JSON object here.
Response
Server-sent event stream.
The response is of type string.
