fix: make ESLint usable for Vue wrappers and library code

[ubugeeei]

Finding

Running ESLint directly produces 197 errors and 28 warnings. Some are real React purity issues, but others are rule-scope mismatches such as React Hooks rules firing inside Vue setup wrappers.

Evidence

• npm exec eslint -- . reports react-hooks/rules-of-hooks in src/lib/vue.tsx setup functions.
• It also reports React Compiler purity/refs errors in Studio/render UI and many no-explicit-any/no-unused-vars issues.

Acceptance criteria

• Scope React-specific lint rules to React component files where they are meaningful.
• Keep real correctness rules enabled for React UI.
• Add a lint script only once it can pass in CI.
