✨ Added

• Added persistent player username storage (player_name) in balances for both SQLite and MySQL.
• Added built-in Portuguese language file: lang/pt.yml.

🔧 Improvements

• Database name validation now allows any practical name up to 64 chars. Rejects only unsafe cases: empty, leading/trailing spaces, control chars, /, , or null char.
• Added automatic DB migration to create player_name on existing balances tables.
• Account load/join flow now refreshes and saves latest player usernames.
• Added new schema default key: database.schema.balances.columns.player_name.
• Added general performance and database/cache handling optimizations.

📘 Documentation

• Updated README and docs to include Portuguese language support.
• Updated database docs to describe stored identity fields (uuid, player_name, discord_id).
• Refined README top layout by moving support/store links under the top images.
• Improved README screenshot section headings for clearer and more consistent presentation.
