GraphCompose v1.5.1

v1.5.1 — 2026-05-05

Dependencies

• PDFBox 3.0.7. Bumped from 3.0.5 to 3.0.7 (Apache PDFBox patch
  release with upstream rendering and security fixes). No
  public-API impact for GraphCompose consumers.

Tooling

• ShapeContainerVisualRegressionTest tolerates the cross-platform
  PDF font-rendering drift that surfaces between Windows-rendered
  baselines and the Linux CI runner (~1-2% pixel diff), via a
  calibrated mismatchedPixelBudget instead of bit-exact comparison.
• DocumentationCoverageTest no longer pins to the structural
  section anchors that the v1.5.0 README slim removed; the guard now
  scans the whole README for canonical-DSL coverage and
  legacy-API leakage in one whole-file pass.

This is a maintenance patch release. There are no public API
changes; v1.5.0 consumers can upgrade with no code changes.
