perf: shorten update-check TTL from 24h to 6h - #172

Rapid-dev cadence: PyPI version cache refreshes 4x/day instead of 1x/day so the upgrade-nudge banner reflects new releases sooner. CACHE_TTL_SECONDS in lifecycle.py drives both the statusline freshness gate and maybe_check_for_update_async()'s spawn decision. Updated stale comment in cli.py _cmd_upgrade for the same constant.
