Add a fast heuristic to detect whether a file may contain React components or hooks before running the full compiler. This avoids the overhead of Babel AST parsing and compilation for utility files, config files, and other non-React code. The heuristic uses ESLint's already-parsed AST to check for functions with React-like names at module scope: - Capitalized functions: MyComponent, Button, App - Hook pattern functions: useEffect, useState, useMyCustomHook Files without matching function names are skipped and return an empty result, which is cached to avoid re-checking for subsequent rules. Also adds test coverage for the heuristic edge cases.
