WattLite 2.2

Signed automatic updates.

• Checks 20 seconds after launch and every six hours; automatic checks can be disabled, and manual checks remain.
• CryptoKit P-256 signature verification and streaming SHA-256; the downloaded zip is verified again before applying.
• A one-time helper waits for WattLite to quit, verifies the new bundle and its code signature, replaces the app, relaunches, and rolls back on failure.
• Read-only locations (DMG, App Translocation) fall back to the download page; update results are reported on the next launch.
• Existing 2.1 users install 2.2 manually once; later versions update in place.
