@ file search is almost unusable in huge code base

Summary

Use "@" to start a file search, it will almost always freeze in large code base. This issue lasts for a long time since I start to use cmdc.

I tested this in two repos, one of it has 42906 files and one of it has 109765 files, the "@" search works but delay like 3-5 seconds on the 42906 one, and will get stuck on the 109765 one.

It seems the solution to file search is not properly implemented in this tool. Switch to codex or claude-code, both of them works seamlessly with "@" file search. Also I believe the current implementation does not ignore some common dependency paths or cache folders.

Expected Behavior

File search works and should be fast

Actual Behavior

File search gets really slow with large code base, and will stuck with huge code base.

Steps to reproduce the issue

Try check out a big mono repo, and install the dependencies fully, then run the file search worfflow.

issue ではファイルもテストも特定されていません。依存関係をインストールした状態で、42,906 個および 109,765 個のファイルを含むリポジトリ上で、Linux と zsh を使って @ file-search ワークフローを再現し、その後、既存の検索エントリポイントを追跡してください。検索が報告された数秒単位の遅延やフリーズなしに応答し続ければ完了です。
