"""Tests for fix/taskmd-description (3 bugs at the analyst pipeline entry/exit):

BUG A: start_pipeline built the analyst .task.md WITHOUT the description body
       (only Title), so analyst received a ~101-byte file and reported the
       "business request is empty". task_desc must now carry the description.

BUG B: issue.updated ships only changed fields, so `name` is usually absent ->
       slug/branch became "untitled". start_pipeline must pull the real name
       from the Plane API (single fetch_issue_fields GET, above the slug build)
       so the branch slug is NOT "untitled".

BUG C: the analyst "artifacts ready" comment used the obsolete ":approved:"
       wording. Under the status-only model it must ask for the **Approved**
       status (not ":approved:", not "In Progress") and link the docs that
       actually exist.
