Vue Debug Guides

This is the debugging reference you wish you had when that computed property mysteriously stopped updating or your watcher started leaking memory. It covers the gnarly stuff: refs not unwrapping in collections, reactive destructuring pitfalls, async watcher cleanup, hydration bugs, and over 100 categorized runtime issues with direct links to solutions. Especially valuable for reactivity debugging hooks, SSR hydration problems, and those weird template ref edge cases that only show up in production. The symptom-first organization means you can jump straight from "child component throws not found error" to the fix without reading Vue internals documentation.
