 * #3168 — Incomplete Task→Agent dispatcher rename causes silent inline fallback.
 *
 * The Claude Code subagent-dispatcher tool is named `Agent`. The `Task*` namespace
 * (TaskCreate, TaskList, TaskGet, TaskUpdate, TaskOutput, TaskStop) is the task
 * tracker — a distinct tool set. GSD workflows were partially migrated and still
 * reference `Task(` and `- Task` in allowed-tools/tools frontmatter in most files.
