1.5.0

Organic directory continents and Auto rotate

• Large folder continents now use deterministic compound S² territories
  instead of filling one uniform circular cap.
• Subfolder cohorts occupy overlapping asymmetric lobes with varied radial
  limits, preserving directory ownership without imposing a disk silhouette.
• Multi-scale connected-ocean erosion carves broad bays and headlands while
  protected member cities remain on land.
• The bottom status rail now includes an always-accessible Auto rotate
  button. It starts or stops a slow camera orbit and stops automatically when
  manual camera interaction begins.

The layout algorithm is now version 5. Existing maps receive one automatic
Initialize, then return to fixed-layout behavior.
