Add JavaScript and TypeScript language support
- Add tree-sitter-javascript and tree-sitter-typescript parsers - Support file extensions: .js, .mjs, .cjs, .jsx, .ts, .mts, .cts, .tsx - Add patterns for Node.js crypto module (createHash, createCipheriv, etc.) - Add patterns for Web Crypto API (crypto.subtle.*) - Add patterns for crypto-js library (CryptoJS.AES, CryptoJS.SHA256, etc.) - Fix panic in import_like_nodes when checking require() calls - Add test fixtures for all three JS/TS crypto libraries Generated with [Claude Code](https://claude.ai/code) via [Happy](https://happy.engineering) Co-Authored-By: Claude <noreply@anthropic.com> Co-Authored-By: Happy <yesreply@happy.engineering>
