remove c0re.operatorPronouns and c0re.contextWindowTokens

Both options are now ignored with a warning (the swarm-peers-removed.nix
shape), so a host that still sets one keeps evaluating.

- operatorPronouns: the agents' system prompt names the pronouns as
  she/her, the value the harness fell back to and the option's default.
  The --operator-pronouns flag, HiveEnv field, meta-flake let binding
  and HIVE_OPERATOR_PRONOUNS env var are gone.
- contextWindowTokens: the per-family defaults (haiku 200000, sonnet
  1000000, opus 1000000) move into hive-agent's harness_state as a
  table; the window the API reports after a turn still wins. The
  --context-window-tokens flag, HiveEnv field and the rendered
  HIVE_CONTEXT_WINDOW_TOKENS_<KEY> env vars are gone.
