Smart Hybrid Sleep (suspend-then-hibernate) on Lid Close

[gregory-chatelier]

Adopt suspend-then-hibernate as the default laptop lid-close behavior to deliver instant wake-up for day-to-day use and zero battery drain when left in a bag or overnight.

Current State in Omarchy: Closing the lid defaults to pure suspend (s2idle). In issues like #9378 ("No lid-shut battery protection when hibernate can't be made to work"), users report battery drain and thermal build-up when laptops stay in suspend inside backpacks.

macOS solves this by sleeping in RAM for the first hour, then transferring RAM state to disk hibernation for long-term storage. Systemd natively supports this behavior via suspend-then-hibernate
