chore(i18n): add Claude-powered translation script and fill missing PO translations

- Add `packages/i18n/scripts/claude.ts` — a Bun script that translates empty PO entries via the Claude Code CLI, supporting batch mode, dry-run, optional AI context from `crowdin-context.jsonl`, and structured JSON output validation
- Add `i18n:claude` root script (`bun packages/i18n/scripts/claude.ts`) as a convenience alias
- Fill all previously empty msgstr entries across de, es, fr, it, pt PO catalogs and recompile `.ts` catalogs
- Polish README with badges (license, CI status, release, language, Crowdin localization) and minor formatting fixes
