v0.6.0

Minor Changes

• acbdaef: Add native Mr. Tree, Radial, Force, and Stress layout providers through the shared
  algorithm registry and ELK adapter. Restore bundled elkjs 0.11.1 algorithm and
  category discovery. Reject unsupported provider settings and graph features.
  Document measured geometry gaps and add a strict rerunnable oracle comparison.
• 7cacb78: Add the independent pele layout algorithm, adapted from Pele under MIT. Preserve measured node and transition-label boxes, and expose coordinated smooth curves through getLayoutRoutes. Support full flat-graph layout in four directions, including cycles, parallel edges, and self-loops; reject unsupported hierarchy, ports, and layout scopes explicitly.

Patch Changes

• 05e1c70: Keep edge labels in their row when a self loop above a node makes room. In RIGHT and LEFT layouts, a label taller than its row's nodes was left behind when the row moved down, so edges into a node with a labeled self loop detoured through the loop's label.
