v1.3.0

Added

• 11 CLI commands for direct terminal access to localization operations:
  • info - show file summary (source language, keys, locales)
  • coverage - translation coverage per locale with percentage table
  • validate - check format specifiers, plural forms, empty translations
  • search - find keys by pattern (case-insensitive)
  • stale - list stale/removed keys
  • add-locale - add a new locale to all translatable keys
  • remove-locale - remove a locale and all its translations
  • export - export translations to XLIFF 1.2 format
  • import - import translations from XLIFF files with validation
  • migrate - migrate legacy .strings/.stringsdict to .xcstrings
  • completions - generate shell completions (bash/zsh/fish/powershell/elvish)
• Auto-discovery: CLI commands automatically find .xcstrings files in the current directory tree - no path required
• --json flag: machine-readable JSON output for CI/CD integration on all commands
• --dry-run flag: preview changes without writing on all mutation commands (add-locale, remove-locale, import, migrate)
• Shell completions for bash, zsh, fish, powershell, elvish via clap_complete

Changed

• service module now public for CLI reuse (removed _test_support re-export hack)
• Extracted service::discovery module from tools::files for file discovery logic reuse
• Extracted service::migrate module from tools::strings for legacy migration logic reuse
• Binary now returns ExitCode instead of Result for proper exit code handling
