🚀 Release v2.0.2: Full i18n Overhaul & WP.org Compliance

This major patch focuses on deeply refactoring the plugin's internationalization (i18n) architecture and ensuring 100% strict compliance with the official WordPress.org Plugin Directory guidelines.

🌍 Internationalization (i18n) & Localization

• English Base Language: Completely refactored the plugin's internal strings to use standard English as the base language (msgid) instead of German, complying with WordPress best practices.
• Hardcoded Strings Removed: Eliminated all hardcoded strings in backend responses (ajax.php) and WP-CLI commands (cli.php), wrapping them in proper gettext functions (__(), sprintf()).
• JavaScript Localization: Implemented wp_localize_script to pass translatable strings to the frontend admin scripts, removing hardcoded UI texts like progress states and completion messages.
• Translator Context Added: Added mandatory /* translators: ... */ PHP comments directly above translatable strings containing dynamic placeholders (%s, %d) to aid the polyglot community.
• Ordered Placeholders: Fixed unordered placeholder variables in translation strings (e.g., using %1$s and %2$s) to allow safe restructuring of sentences in different languages.
• Updated Language Packs: The .po and .mo files for German (de_DE), English (en_US), and Japanese (ja) have been completely synchronized with the new English base strings.

⚙️ Core & WordPress.org Compliance

• Text Domain Unification: Conducted a comprehensive sweep to ensure the henkan-webp-avif-converter text domain is used exclusively and consistently across all PHP files to match the official plugin slug.
• Global Variable Standardization: Refactored internal global variables to remove leading underscores (e.g., changed $_henkan_last_error to $henkan_last_error), strictly adhering to WordPress naming conventions.
• Stable Tag Alignment: Synchronized the Stable tag in README.md to ensure it accurately reflects the main plugin file header version.
• Asset Restructuring: Removed official WordPress.org directory assets (banners and icons) from the core plugin distribution zip. These will be managed exclusively via the .org SVN assets/ directory going forward.
