Magnemo 0.6.4 — the words

• The engine tells the truth about Python: requires-python is >=3.11, as the README, the site and the paste
  already say. pip install on 3.10 now refuses with the standard message.
• Found by running the suite on 3.11: a vault path given AFTER flags (magnemo promote <id> --by NAME <vault>,
  magnemo stage … <vault>) was rejected as an unrecognized argument on Python 3.11 (3.12+ parsed it). The CLI now
  reads one leftover word as the vault on every supported Python.
• The words: every sentence a reader meets — the README, the docs, this file, the CLI's help and messages, the MCP
  door's replies, the boot pack, the vault's own README — now says "you", "a person" or "the keyholder". The door's
  refusal reads "an agent seat cannot sign as a keyholder"; the stage reply reads "Awaits KEYHOLDER review"; the caps
  read "keyholder-only". Words only: the config key trust.humans, every identifier, ledger field, file format, tool
  name and the rule itself (promotion and publish are never an agent's) are unchanged.
• magnemo --version prints the version (it was missing; the release drill asked for it).
