docs(hooks-claude): current-state comment wording caught in review

Two Codex nitpicks, comment-only (no behavior change):
- the SubagentStop-cwd regression test comment narrated "The bug" / "Proven to
  regress" — rewrote to state the invariant it checks, not the history.
- the subagent/end listener comment said "no session is passed"; with a child a
  session IS passed — corrected to "no `turn` is passed (so no hook/* records)",
  which is the actual reason runPoint has nothing that can reject.
