Feat/i18n

[mojimoon]

This pull request significantly expands the codebase to support full multi-language output for all game data, not just English and Chinese. It introduces a new list of supported languages, updates all data structures and effect text generation to handle all languages, and adds utilities to prune data for per-language output. The changes ensure that every relevant text field (names, effect descriptions, UI strings, etc.) is now available in all supported languages and can be efficiently reduced to a single language for frontend consumption.

Multi-language support and data structure updates:

• Introduced LANGS (list of supported languages) and LANG_META (native language names) at the top of main.py for consistent language handling throughout the codebase.
• All translation lookups and effect text generation now produce dictionaries keyed by every language in LANGS, rather than just 'en' and 'zh'. This affects translation loading, merged translation handling, effect text dicts, and special-case metadata. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10]

Per-language pruning utilities:

• Added a suite of _prune_* functions to reduce multi-language data structures to a single language, including effect texts, special metadata, weapons, items, characters, and sets. The main entry point is prune_data_for_lang, which produces a data dict containing only the selected language's text and UI strings for frontend use.

UI strings and metadata:

• Added load_ui_strings to load per-language UI strings and integrate them into the per-language data output.
• Ensured UI strings, section names, and tag translations are also pruned to the selected language in the final output.

Consistent multi-language naming:

• All weapon, item, and character entries now include names for every language (e.g., name_fr, name_ja, etc.), and the pruning logic extracts only the relevant name for the selected language. [1] [2] [3] [4]

Improved translation merging logic:

• The merged translation loader now pulls all available languages for matched entries, not just English and Chinese, by referencing the candidate rows in the game's translation CSVs. [1] [2]

These changes lay the groundwork for robust multi-language support across the entire data pipeline and frontend.
