Use when Vite dev startup is slow, HMR is not invalidating, the build emits chunks larger than expected, or you are authoring a Vite plugin. Triggers: "[plugin:..] failed", "Failed to resolve import", externalize warnings, dependency pre-bundling errors, lib mode + code splitting, ssr externals confusion, "Cannot find package" only in build, manualChunks tuning, optimizeDeps include/exclude tuning, rollup-plugin-visualizer review, --profile flag, configResolved/handleHotUpdate hook authoring.
