The in-memory metrics buffer was changed from 1000 to 86400 points per metric to support 30-day sparklines, but this pre-allocated ~18 MB per guest (7 slices × 86400 × 32 bytes). With 50 guests that's 920 MB — explaining why users needed to double their LXC memory after upgrading to 5.1.0. - Revert in-memory buffer to 1000 points / 24h retention - Remove eager slice pre-allocation (use append growth instead) - Add LTTB (Largest Triangle Three Buckets) downsampling algorithm - Chart endpoints now use a two-tier strategy: in-memory for ranges ≤ 2h, SQLite persistent store + LTTB for longer ranges - Reduce frontend ring buffer from 86400 to 2000 points Related to #1190
