Subject: [PATCH] perf(cli): enable compile cache and defer getCliVersion for
 serve (#5938)

Enable Node.js compile cache (module.enableCompileCache) in the serve
fast-path so V8 bytecode is cached across daemon restarts. Start
getCliVersion() as a non-blocking promise and resolve it in parallel
with the runtime module loads inside buildRuntime(), removing it from
the pre-listen critical path.
