v1.19.0

• Streamlined the README around install, first preview, and official AlbumentationsX documentation, with deeper
  operator material moved to a curated documentation index.
• Added a stable albumentationsx-mcp.mcpb release alias for the latest full release while keeping versioned MCPB
  artifacts and preventing prereleases from becoming GitHub latest.
• Added privacy-safe, release-aware aggregate PyPI and GitHub growth reporting with complete release pagination,
  explicit rolling Traffic windows, and no runtime telemetry.
• Added manual-only campaign cards for classification robustness, detection bbox safety, and segmentation mask safety,
  each with a prompt, artifact, attributed destination, and success signal.
• Added the canonical AGPL-3.0-or-later license text and aligned public release, host-proof, Registry, plugin, and
  desktop-extension metadata.
