1. Fuzzing Tests for All Inputs

Task 1.1: AST Parser Fuzzing (Babel Input)

Priority: 🔴 HIGH
Time Estimate: 45-60 minutes with AI
Dependencies: None
Tools Needed:
- @jazzer.js/core (fuzzing framework)
- fast-check (property-based testing)
- jsfuzz (JavaScript fuzzer)

Installation:

pnpm add -D @jazzer.js/core fast-check

Steps:

Create src/__tests__/fuzzing/babel-parser.fuzz.test.ts
Generate malformed JSX/TSX code samples (unclosed tags, invalid attributes, broken syntax)
Fuzz test with deeply nested JSX (1000+ levels)
Test Unicode edge cases (emoji in component names, RTL text, zero-width characters)

Test binary/null bytes in code strings

Success Criteria:

Plugin gracefully handles all malformed input without crashes
No uncaught exceptions in 100,000+ fuzz iterations
Maximum memory usage stays below 500MB per test

Implementation:
