test(canvas): add pure-function tests for resolveRuntime and canvas-topology utilities

- preflight-resolveRuntime.test.ts: resolveRuntime from deploy-preflight.ts
  covering explicit runtime-map entries, identity fallback, -default suffix
  stripping, edge cases (empty string, multiple suffixes).
- canvas-topology-pure.test.ts: sortParentsBeforeChildren (topological
  sort, orphan handling, no-op, non-mutating), defaultChildSlot (2-col
  grid), childSlotInGrid (variable-size siblings, uniform-grid fallback),
  parentMinSize (0–5 children, grid dimensions), parentMinSizeFromChildren
  (variable sizes, empty array, width/height correctness).
