Smart Solver - Full Checked

INSTALL:
1. Extract the ZIP.
2. Open chrome://extensions/
3. Turn on Developer mode.
4. Click Load unpacked.
5. Select the folder SmartSolver-Full-Checked.
6. Refresh the quiz page.

BEHAVIOR:
- On page load the extension verifies that http://smrchain.online/pass.txt exists and is readable.
- If pass.txt cannot be loaded or is empty, the extension uninstalls itself from Chrome.
- A password box appears automatically after successful server validation.
- The entered password is compared with the current text in pass.txt.
- After successful login, "פתור" and "פתור הכל" are shown.
- "פתור הכל" attempts to solve and click the next-question control repeatedly.
- 10 seconds after "פתור הכל" finishes, the extension uninstalls itself from Chrome.
- Chrome cannot delete the unpacked source folder from your Windows disk; self-uninstall removes it from Chrome only.

SHORTCUT:
- Reliable shortcut: Ctrl+Shift+1
- The content script also attempts Ctrl+1, but Chrome normally reserves Ctrl+1 for switching to tab 1.

DATABASE:
- questions.json includes the three supplied databases.

NEW: After 'פתור הכל' finishes, the floating solver UI closes automatically. No X click is required.

FIX: At exactly 10 seconds after completion, the floating UI closes locally, then Chrome self-uninstall proceeds.

QUESTION-BY-QUESTION ENGINE:
- Finds the active question container.
- Matches by question text + answer options + image URL/name when present.
- Supports radio answers and multiple checkbox answers.
- Clicks the next-question control and waits until the question actually changes.
- Database validation: 706 questions, 250 with images, 0 multi-correct entries.
