feat(verify): use content script + DOM modification pattern

Browse Source 
Implementacja wzorca: background → event → content script → DOM

Jak działa:
1. Background script tworzy testową stronę (browser.tabs.create)
2. Content script wstrzykiwany do tej strony (<all_urls>)
3. Content script modyfikuje DOM (document.body.setAttribute)
4. Content script loguje marker do konsoli
5. Test grep'uje logi za markerem

To dowodzi że cały stack rozszerzenia działa:
- background.ts wykonany
- browser.tabs.create() sukces
- content script injection sukces
- DOM modification sukces

Pełna weryfikacja bez WebDrivera!
