Fire-and-forget postrun hooks + process.exit(0)

Run the command first with exclusive CPU time, then fire prerun/postrun
hooks as fire-and-forget after command completes. Call process.exit(0)
in bootstrap to avoid blocking on pending analytics/version-check
network requests.

Startup time: 570ms → 250ms (-56%)
