v0.9.4

version 0.9.4

• GUI: the Train tab now reuses the weighted training progress tracked by the
  CLI pipeline, showing the active phase in the status legend and a cleaner
  visual-only progress bar.
• Metadata/docs: synchronized package version references across the codebase,
  documentation, and citation metadata for this patch release.

version 0.9.3

• CLI: added explicit run, generate, and gui subcommands, legacy
  compatibility warnings, and a dedicated synthetic-data generation mode.
• Packaging/API: aligned runtime dependencies, added the causalexplain
  console entry point, and lazy-loaded heavy package modules to keep imports
  lightweight.
• Reliability/docs: fixed generator edge-case handling for small graphs,
  clarified that PC and CAM remain unsupported public APIs, and refreshed the
  README/quickstart/install docs for the current workflow.

version 0.9.2

• ReX: added SHAP budget batching, bootstrap SHAP caching, and HPO
  optimization controls.
• CLI/GUI: renamed optimization options and exposed the new settings in the
  Train tab and command line.
• Stability: fixed the bootstrap-cache and gradient SHAP regressions found
  during merge validation.
