v0.3.0

What's Changed

• v0.3 by @volfiros in #4

Full Changelog: v0.2.0...v0.3.0

Summary

Auth

• Google OAuth via popup window — OAuth now opens in a small popup instead of a full tab, keeping the extension popup alive during the auth flow
• Improved auth callback page — redesigned with pending / success / error states and a manual close button on success
• Removed background auth watcher — OAuth completion is now detected by session polling directly in the auth page, removing unnecessary background script complexity

API Key UX

• Read-only key display — API key field is now non-editable and non-selectable; key is shown masked by default
• Connected button group — show/hide, copy, and clear actions grouped into a single cohesive control when a key is set
• Paste button — when no key is set, a single Paste button reads directly from clipboard
• Clipboard permissions — added clipboardRead and clipboardWrite to manifest permissions to support paste/copy

Bug Fixes

• Fixed API key not clearing geminiService when removed
• Fixed whitespace-only API keys being accepted (now trimmed on read)
• Fixed clipboard copy using .then/.catch — migrated to async/await
• Fixed settingsRef type to use canonical TranslationSettings property names
• Fixed stale .env error message referencing old flow instead of Settings UI
• Fixed PID guard in dev script cleanup to handle early interruption safely

Chores

• Cleaned up .env.example files — clarified self-hosting context, removed unused BETTER_AUTH_URL, pointed at shared Convex deployment for contributors
• Removed unwanted server/.env.example from extension repo
