Add common.* keys for reusable translations: - common.label.* - UI labels (error, done, status, version, etc.) - common.status.* - status words (running, stopped, dirty, synced) - common.error.* - error messages (failed, not_found, working_dir) - common.flag.* - CLI flag descriptions (registry, verbose, etc.) - common.count.* - count templates (failed, passed, skipped) - common.result.* - result messages (all_passed, no_issues) - common.progress.* - progress messages (running, checking) - common.hint.* - help hints (install_with, fix_deps) Update all cmd/* files to use common keys instead of duplicated command-specific keys. Reduces translation maintenance burden and ensures consistency across the CLI. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
