perf: update bundle size thresholds after lazy-loading selections

Minimal/basic bundles grow ~2 KB from the lazy wrapper overhead (they
still include the selections module since it's registered in full core).

Updated sizes (minified):
  lite:    937,269 bytes (915 KB)  ← saved 34 KB
  minimal: 1,076,875 bytes (1,052 KB)  +1 KB (wrapper overhead)
  basic:   1,185,641 bytes (1,158 KB)  +1 KB (wrapper overhead)
