Ability to set token/time based timeouts

[maschwenk]

When using Claude unattended in CI, it can be hard to setup guardrails that limit uncontrolled usage. We've been using naive timeouts as a means of achieving this, but this is not as fine-grained as it could be, because not all time spent in Claude Code costs us money. I'd rather have a 30 minute timeout, but set a $ cap for a given session.

In unattended mode it must be scripted - so why not just have a project command /project:enforce-limits that runs /costs and analyzes the output? Long-term it should just be a built-in command like /cost or /compact - e.g. /enforce-limits which could be called and uses a config variable
