v1.1.0

Adds a command input so the action can run the CLI's read-only commands, not only translate.

command: check fails the job when a locale is missing or stale. command: diff fails it when there are pending changes, and lists the keys. Both are read-only: no provider call, no API key, no quota, so they work on pull requests from forks.

command defaults to translate, so existing workflows are unaffected. dry-run applies to translate only and is rejected with the other commands rather than ignored.
