chore(changesets): prune retired-package references from pending changesets

- 3 changesets referenced only retired packages (agent-core-v2,
  agent-core) and described retired implementations (rust-loop era) —
  deleted (fix-v2-version, i18n-agent-core, rust-engine-default-everywhere)
- 3 more had retired packages mixed into valid frontmatter — stripped
  (cli-i18n-hardcoded, fix-i18n-locale-propagation,
  i18n-shared-unification), keeping their user-facing entries
- 53/53 changesets now have valid frontmatter with no retired-package
  references, so the next changeset version/publish cannot fail

 Replace hardcoded English strings in CLI command descriptions with proper i18n calls so `kimi --help` respects the configured locale. Fix locale propagation from the CLI shell to agent-core.
