fix: lint-staged error (#617)

## Description

In a recent commit, the command `"cd codex-cli && pnpm run typecheck"`
was updated to `"pnpm --filter @openai/codex run typecheck"`.

However, this change introduces an issue: 
when running `pnpm --filter @openai/codex run typecheck`, it executes
`tsc --noEmit somefile.ts` directly, bypassing the `tsconfig.json`
configuration. As a result, numerous type errors are triggered,
preventing successful commits.
