When a new agent is created, automatically create an initialization issue
assigned to it so the agent starts working immediately. The issue
description incorporates the workspace context field, giving the agent
background info to set up its environment (clone repos, etc.).
Also adds workspace context to the task context snapshot for all tasks,
and renders it in the daemon prompt so agents always have workspace
background when executing.
