[ahokusa] Migrate to TypeScript and ChannelLimitedBot, add #tsgbot-games support

[Copilot]

Migrates ahokusa bot to TypeScript and integrates ChannelLimitedBot for #tsgbot-games channel support per #1099.

Changes

• TypeScript migration: Converted ahokusa/index.js (537 lines) to ahokusa/index.ts (620 lines) with proper type annotations
• ChannelLimitedBot integration: Created AhokusaBot class extending ChannelLimitedBot, following patterns from crossword (crossword: gamesチャンネルからの起動に対応 #1109), character-quiz (character-quiz: ChannelLimetedBotクラスを使用するよう修正 #1122), and achievement-quiz (Refactor achievement-quiz to use ChannelLimitedBot for #tsgbot-games support #1124)
• Multi-channel support: Configured allowedChannels to accept both CHANNEL_SANDBOX and CHANNEL_GAMES, with automatic redirection and ephemeral messages for disallowed channels
• Wake word handling: Extended regex to match all game commands including @ahokusa pattern for custom board initialization and hints
• Progress notifications: Integrated deleteProgressMessage() calls on game completion and failure states

Key Implementation Details

The bot handles both wake-word game initialization and in-thread gameplay:

class AhokusaBot extends ChannelLimitedBot {
  protected override readonly wakeWordRegex = /^(あほくさスライドパズル|寿司スライドパズル( [3456])?|千矢スライドパズル|スライドパズル爆破|あ　ほ　く　さ|@ahokusa\b)/;
  protected override readonly allowedChannels = [process.env.CHANNEL_SANDBOX!, process.env.CHANNEL_GAMES!];

  protected override async onWakeWord(message: GenericMessageEvent, channel: string): Promise<string | null> {
    // Game initialization logic
  }

  private async onThreadMessage(event: MessageEvent) {
    // In-thread move processing (上下左右wasdhjkl commands, もう一度, 不成立, etc.)
  }
}

Tests updated to TypeScript with added coverage for 千矢スライドパズル variant.

動作確認済み。なお、競争力の高いBOTではないと判断したのでゲーム進行中のsandboxへの通知は実装しなかった

📋 Review Summary

うにゃ！このプルリクエストは ahokusa ボットをTypeScriptに移行して、ChannelLimitedBot を使うようにする変更だにゃ。全体的にうまく移行できていると思うにゃ！

🔍 General Feedback

• ChannelLimitedBot の機能と重複するチェックがいくつかあったにゃ。もっと ChannelLimitedBot を活用すると、コードがもっときれいになると思うにゃ！
• user や invert の戻り値に ! （非nullアサーション）を使うのは、ちょっと危険な場合があるにゃ。ちゃんと値があるか確認する方が安全だにゃ。
• console.trace() はデバッグにはいいけど、本番環境では注意が必要だにゃ。
