- Uninstall zustand, tailwindcss, autoprefixer, tweetnacl-util (all
unused); README no longer advertises Tailwind/Zustand.
- Fix stale 'Tone' -> 'Explain' copy in Options.
- Add .nvmrc/engines/packageManager (Node 22 to match CI).
- wxt.config.ts reads manifest version from package.json so the two
can never drift.
- Ignore *.zip build artifacts.
- Skip the two e2e specs with literal [EXTENSION_ID] placeholders
(cannot pass; TODO references the e2e-ID-resolution task).

- LEXAI-13: TweetNaCl secretbox encryption for API keys in Options + background
- getOrCreateEncKey() generates per-device 32-byte key stored in chrome.storage.local
- Keys saved as nonce+ciphertext (base64) under apiKeyEnc
- Backward compat: falls back to plaintext apiKey if no encrypted key found
- Lock icon 🔒 shown in Options label when key is encrypted
- LEXAI-11: Right-click context menu with Fix, Rephrase, Shorten, Expand, Tone
- Registered via onInstalled in background service worker
- Sends lexai-context-menu message to content script
- Content script listener added at bottom of main()
- LEXAI-12: Tone analysis button added to floating toolbar (teal #2dd4bf)
- Analysis-only: showModal called with null originalText = no Replace button
- Tone system prompt updated to pure analysis (no rewrite)
