drop the operator pronoun sentence from the agent system prompt

Not every swarm's operator is she/her. The prompt now names no pronouns
and tells agents to say "the operator"; pronouns will come from a
per-operator profile setting. The operatorPronouns removal warning and
claude-invocation.md say the same.
