[3.0.0] - Unreleased

PO Plural Forms Support: Complete support for PO plural forms (msgid_plural, msgstr[n])
- Multi-form plural entries with proper index validation
- Complex language support (Arabic 6-form, Russian 3-form, etc.)
- Robust boundary detection for consecutive plural entries
- Context + plural combination support

PO Parser Improvements: Enhanced parsing reliability and error handling
- Fixed multi-entry parsing boundary detection issues
- Improved context + plural key generation (notification.one@email format)
- Added msgstr[0] validation requirement for plural entries
- Enhanced error detection for malformed PO syntax (msgid_plural without msgid)
- Fixed string generation format issues in tests (literal \n vs actual newlines)

CLI Migration: Extracted CLI functionality to separate g18n-dev package
- Core g18n library is now browser-compatible (removed Node.js dependencies)
- CLI tools moved to g18n-dev: generate, generate_nested, generate_po commands
- Development dependencies removed: argv, shellout, simplifile, tom, filepath
- Breaking change: CLI functionality requires separate g18n-dev package installation

PO File Support: Complete gettext PO/POT file format support
- translations_from_po() - Import PO file content into g18n translations
- translations_to_po() - Export g18n translations to PO format
- generate_po CLI command - Generate Gleam modules from PO files
- Full PO format features: contexts (msgctxt), multiline strings, escape sequences
- Comprehensive comment support: translator notes, source references, flags
- Performance optimized for 1000+ translation entries
- Seamless integration with existing g18n workflow and features

BREAKING: Fixed translations_from_nested_json() - Now properly handles deeply nested JSON structures
BREAKING: Fixed ordinal suffix logic - ordinal_suffix() now includes position in output
BREAKING: Fixed currency positioning for Spanish, French, and Italian locales (now displays “24€” instead of “€24”)
Fixed number precision formatting - 0 precision now shows “24” instead of “24.0”, 2 precision shows “24.00” instead of “24.0”
Fixed currency spacing - Spanish uses no space (“24€”), while French/German/Italian use space (“24 €”)
Improved nested JSON conversion using decode.recursive for better performance

RTL/LTR Text Direction Support: Added TextDirection type, get_text_direction(), is_rtl(), get_css_direction()

Complete Pluralization Coverage: Added plural rules for 12 languages (Spanish, French, German, Italian, Arabic, Chinese, Japanese, Korean, Hindi)
Context-Sensitive Translations: Added TranslationContext type, translate_with_context(), add_context_translation()
Advanced Translation Features: Number formatting, date/time formatting, validation tools
CLI Code Generation: Command-line tool for generating Gleam modules from JSON translation files
