Subject: [PATCH] Skip LastAgent in Result JSON serialization
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Result.LastAgent is *Agent, which holds only unexported fields. The
default json.Marshal renders it as an empty object, which is misleading
when persisted alongside the agent run.

Tag LastAgent as json:"-" and add explicit lowercase JSON tags to the
remaining fields so the serialized shape is stable for callers that
read the persisted result column.
