[octas] Migrate to ChannelLimitedBot to support #tsgbot-games

[Copilot]

The octas bot was hardcoded to CHANNEL_SANDBOX. This migrates it to ChannelLimitedBot, enabling activation from #tsgbot-games with progress notifications posted to #sandbox.

octas/index.ts

• Convert flat function export to OctasBot extends ChannelLimitedBot
• Set wakeWordRegex = /^octas$/i, username = 'octas', iconEmoji = ':octopus:'
• Add channel: string | null to State; set on game start, cleared on halt
• Replace all process.env.CHANNEL_SANDBOX hardcoding with this.state.channel
• Replace slack.chat.postMessage({..., username, icon_emoji}) with this.postMessage()
• Override onWakeWord: starts/cancels game, returns thread ts for progress message tracking
• Override onMessageEvent: calls super (wake word handling), then routes thread replies to waitForPlayers/processHand
• Call deleteProgressMessage(this.state.thread) on game end

class OctasBot extends ChannelLimitedBot {
    protected override readonly wakeWordRegex = /^octas$/i;
    protected override readonly username = 'octas';
    protected override readonly iconEmoji = ':octopus:';

    protected override async onWakeWord(message: GenericMessageEvent, channel: string): Promise<string | null> {
        if (this.state.isHolding) { /* cancel current game */ }
        if (message.thread_ts) return null;
        return await processQueue.add(() => this.launch(channel)) ?? null;
    }
}

octas/index.test.ts

• Set process.env.CHANNEL_GAMES = slack.fakeChannel (bot now defaults to CHANNEL_GAMES)
• Add jest.mock('../lib/slackUtils') (required since ChannelLimitedBot imports from it)

<issue_title>[octas] #tsgbot-games 対応 & ChannelLimitedBotクラスを導入</issue_title>
<issue_description>Issue #1099 の対応の一環として、 octas BOTの改修を行う。

Slackの #tsgbot-games チャンネルからの起動に対応できるようにする。また、 lib/channelLimitedBot.ts で定義されたChannelLimitedBotクラスを利用し、起動チャンネルの指定と進行中のゲームの通知を導入する。

改修にあたっては、すでに行われた以下の3つのBOTの同様の修正の修正内容を必ず参照し、これらのスタイルを可能な限り踏襲する。

なお、対象のBOTがJavaScriptで書かれている場合は、今回の改修でTypeScriptに書き換える必要はない。このプロジェクトではJavaScriptとTypeScriptを混在させることができる。また、そのほか改修に関係ない改良を加える必要はない。
