🌍 Polish for the multi-language release

Six fixes from feedback after the 2.0 launch, plus the /cg lang command itself now speaks all 7 languages.

Fixes

• Diacritic-insensitive answers - Answer "București" with or without the ț, "José" with or without the é, "München" with or without the ü. The plugin normalizes accents so players on any keyboard layout can win. This was a big problem for non-English servers in 2.0; it's gone now.
• GUI no longer lag-spikes - Opening the leaderboard GUI used to hit the database synchronously every time. Now it uses the cached top (already updated off-thread by the PAPI cache), so opening GUI on a busy server is instant.
• Reward command errors don't tank the chain - A single broken reward command (typo in config, plugin not loaded, etc.) used to throw an exception and skip the rest of the rewards for that win. Now each command is isolated with a try/catch and a clear warning in console.
• /cg lang stops the active game - Switching language mid-game used to leave a question generated in the old language with an answer in the new one. Now the active question is cancelled before the switch.
• /cg lang now speaks the active language - Ironically, the command that changes language was the only one with hardcoded English messages. Fixed in all 7 bundled languages (with skeleton PL/DE/FR falling back to English as expected).
• "No data yet" leaderboard message is now translatable - One last hardcoded English string in the GUI is now in gui.leaderboard-empty across all language files.

Small improvements

• /cg lang now appears in the help menu (was implemented but not advertised in 2.0)
• Internal comments cleaned up - no more stale references to the old messages.yml file

No config changes needed. Drop in the new jar and reload (or restart).

If you have custom translated lang/<code>.yml files, the new keys (command.lang-status, command.lang-reloaded, command.lang-switched, command.lang-not-found, gui.leaderboard-empty) fall back to English until you translate them - no breakage.
