v2.0 — Major upgrade

NEW
• Five generation styles: Friendly, Leetspeak, Pronounceable, Alphanumeric, PIN
• Themed wordlists: Animals, Tech, Fantasy, Nature, or mixed
• History tab — last 20 generated, one-click reuse
• Favorites tab — star usernames you want to keep
• Strength meter — live entropy estimate in bits
• Prefix / suffix inputs
• Keyboard shortcut: Cmd/Ctrl+Shift+U fills the focused field anywhere
• Right-click any input → "Fill with random username" / "Copy random username"
• Dark mode (follows system preference)
• In-page suggestion popup now has a regenerate button and Esc-to-dismiss

IMPROVED
• Cryptographically-secure randomness (crypto.getRandomValues) replaces Math.random
• Smarter field detection: reads autocomplete attribute and <label> text, skips search/OTP/credit-card/captcha fields
• React/Vue compatible value injection (native setter)
• Wordlists expanded ~4×
• Popup UI rebuilt — tabs, fixed unreadable select, larger click targets

FIXED
• Suggestion popup no longer appears on search bars, phone fields, or one-time-code inputs
• Select dropdown was unreadable in light mode (white text on white)
• Service worker now compatible with both Chromium MV3 and Firefox MV3 (scripts fallback)
