Added a manual "Check for Updates" button and status in the About screen, and a direct download link for the update banner instead of always sending you to the website.
Fixed stale About-screen text that incorrectly described this as a personal preview build with no real licensing. Licensing has been live since 0.7.0.
Hardened license activation against malformed server responses.
Real Lemon Squeezy license-key activation and validation, so the trial actually locks after 14 days without a valid key. In-app update check with a banner when a newer version is available.
Initial build: calendar picker, Preview vs. Copy Events Now, Keep Syncing with 5m/30m/1h/24h interval, Options (update existing events, skip all-day events, activity log), local EventKit-based sync engine with duplicate detection, local 14-day trial.
