Add /cc:<command> to forward Claude Code slash commands (v0.1.20)

[t2tx]

概要

Iris 自身のコマンドは / 名前空間(/help /status …)を使うため、Claude Code 側のスラッシュコマンドを Iris 経由で叩けませんでした。/cc: エスケープを追加します。

/cc:mycommand arg のように送ると、Iris は /cc: を剥がして /mycommand arg を既存の forwardToClaude 経路でセッションの Claude プロセスへ転送します。

仕様

• カスタムコマンド / スキル(.claude/commands/*.md)は stream-json モードで Claude が展開するため 動作する。
• 組み込みの対話コマンド(/context /compact /clear /cost 等)は headless モードで利用不可のため 何も起きない（/help と usage hint に明記）。
• Iris の既存コマンドとは名前空間が分離(例: /cc:help は Iris の /help ではなく Claude の /help を転送)。

検証

• 実機(dev、DM + チャンネル mention 両方): 一時カスタムコマンド /cc:iris-cctest を送り、Claude が展開・実行してコマンド本文どおりの出力を返すことを確認。
• pnpm verify 全通過、122 tests pass(/cc: の挙動テスト 4 件追加)。

Walkthrough

Adds /cc:<command> [args] handling in src/commands.ts to forward commands to Claude Code, with a usage response for bare /cc:. Help text, tests, and the package version are updated.

/cc: Command Forwarding

Layer / File(s)	Summary
Prefix detection and forwarding src/commands.ts	Defines CC_PREFIX, extends handleCommand to parse /cc:<rest>, returns usage text for bare /cc:, and forwards the remainder to Claude as /<rest>. Adds /cc:<command> [args] to cmdHelp().
Forwarding tests src/commands.test.ts	Adds unit tests for argument forwarding, /cc:help behavior, and bare /cc: returning usage without forwarding.
Version bump package.json	Bumps version from 0.1.19 to 0.1.20.
