Function check_for_update

src/global.rs:269–311

Best-effort version check with 5-minute network cache. If `skip_cache` is true, always fetches from GitHub (used during sync where the call runs in parallel). If `skip_suppression` is false, the warning is suppressed for 15 minutes after it was last shown; if true it is always shown (used for status).
