rbcc 0.2.1

Documentation

• Added a complete, executable getting-started vignette that presents the paired-measurement workflow, the four decision costs, all supported chart families, exact optimization, alternative optimizers, optional parallel grid evaluation, and the multivariate example.
• Expanded the README with the vignette entry point and CRAN-oriented examples.
• Updated the package citation to version 0.2.1.

Quality assurance

• Added an independent regression test that compares the exact optimizer with exhaustive evaluation of all empirical X-bar threshold events.
• Added a cross-platform regression test that checks equality of sequential and parallel grid-search results. The default check uses one worker for maximum portability; a two-worker path can be enabled with RBCC_RUN_PARALLEL_TESTS=true.

Compatibility

• No exported function signatures or default chart calculations changed in this release.
