test(06-16): add CoreState save/load perf suite across item scales and compressions
- saveables.perf.ts: 9 cases = 10/100/1000 items x No/Low/High compression - each sample round-trips all 5 registered saveables through saveState/loadState - synthetic item definitions via addTile -> itemStore.addItem -> equipment.add/addItem - warmup 3 + 20 samples, median/min/p95 via console.table, no assertions
