Avodek: Private Browser + AI

This update fixes sign-in and dark-mode problems, sharpens the safety warnings, and makes the browser faster and steadier. - Signing in works reliably again: Gmail and other login pages are no longer misread as "broken" and reloaded, Reddit and similar app-style sites load correctly, and you stay signed in as you move between sites and tabs. - Fixed "Apply dark mode to websites" hiding text on some pages, and a loading spinner that could get stuck when turning it off. - Phishing and lookalike-site warnings now appear reliably in cases that were previously missed, and choosing "Visit Anyway" correctly lets you through instead of looping back to the warning. - Certificate warnings now correctly identify the problem — expired, self-signed, name mismatch, or untrusted — and are final for sites with an invalid certificate. Site and download warnings share one consistent design, and returning from a blocked page brings back the page you were on. - AI chat now handles long conversations, so extended chats keep responding instead of stopping partway through. - Added a quick Clear Data option to the Browse menu, and "Clear All Data" now also resets the tracker and privacy counts on your start page. - The keyboard no longer covers the address bar, plus faster tab switching and app launch, lighter memory use on image-heavy pages, and improved overall stability.
