Fix post-merge daemon projection test isolation

[chubes4]

Summary

• remove the process-global runner continuation registration test that contaminates parallel test state
• restore the missing Command import required by workspace cleanup code
• apply current formatter output

Follow-up to #12906.
Relates to #11090.

Verification

• cargo fmt --check
• cargo check
• focused continuation-provider test build exceeded the local five-minute command budget before executing; no test failure was reached

AI Assistance Disclosure

OpenAI gpt-5.6-sol used through OpenCode to compare the merged branch with current main, identify the CI aggregation root cause, prepare the minimal follow-up, and run verification. Chris Huber remains responsible for the change.
