Summary

This pull request resolves three critical bugs discovered during deep technical analysis of AgentLens:

1. Issue fix(core): Fix CSS selector generation in differ to escape Tailwind and special character classes #13: CSS selector generation in differ.ts now safely escapes Tailwind CSS atomic utility classes (such as w-1/2, max-w-[500px], text-[14px]) using [class~="..."] and normalizes numeric IDs (e.g. [id="123-product"]), preventing DOMException: Not a valid selector errors in the Chrome Extension ghost overlay.
2. Issue fix(core): Preserve URL query parameters in robots.txt path matching per RFC 9309 #14: scorer.ts now preserves URL search/query parameters when evaluating against robots.txt, fully conforming to RFC 9309 Section 2.2.2 requirements.
3. Issue fix(cli): Safe JSX/TSX and Astro code generation escaping in compiler #17: The build compiler in compiler.ts now encapsulates component text inside JSX/Astro string expressions ({JSON.stringify(...)}), preventing compiler syntax errors when brand names or product specifications include curly braces ({, }) or angle brackets (<, >).
