resolver

Node.js has different resolve algorithm for require (hereinafter, called "CJS resolver") and import (hereinafter, called "ESM resolver").

Vite needs to support both of them.

times
- start up time: the time from "the command is executed" to the time "load event is triggered in browser".
- root HMR time: the time from "the root file is changed" to the time "that file is executed in browser".
- leaf HMR time: the time from "the leaf file is changed" to the time "that file is executed in browser".
cold/hot start
- cold start: the dependency optimization cache is deleted before each run
- hot start: the dependency optimization cache exists by each run
