## Description

Version 0.4 - Form Hack Reloaded (MIT Fork)

<strong>What's New:</strong>
- Toggle hidden form inputs ON/OFF with persistent state across page reloads
- Green ● (active) / Red ● (inactive) badge visual feedback
- Auto-applies on page load via content script

<strong>How to Test:</strong>
1. Install → Click icon on any page → Red ● (inactive)
2. Click again → Green ● (active) → hidden &lt;input type="hidden"&gt; become visible text fields with gray labels
3. Refresh page → fields stay visible (persistent)
4. Click → Red ● → fields revert to hidden

<strong>Eval Usage (Safe):</strong>
- Required for dynamic code injection to toggle input types on arbitrary pages
- Only modifies DOM (input type/class + labels), no data exfiltration
- Matches original Form Hack behavior (MIT licensed upstream)

<strong>Test Page:</strong> Any form with hidden inputs (e.g., login pages, checkout forms)
