fix: use process.exitCode instead of process.exit() in runners so finally cleanup runs

process.exit() terminates the Node.js process immediately without executing
pending finally blocks. All five runners (claude, openai, crewai, nanobot,
openclaw) write temporary files or directories then call process.exit() inside
a try block, so the finally cleanup is always skipped.

Replace process.exit(N) with process.exitCode = N; return so the finally
block executes and removes temporary files before the process exits naturally.
This prevents system prompt content, agent configs, and API key material
written to /tmp from persisting on disk indefinitely.
