AnovaCraft 0.1.0

The first public release of AnovaCraft: a desktop application for
statistical analysis, design of experiments and predictive modelling, with
linked brushing across every plot and data view.

• Analyses under Describe, Compare, Model, Multivariate, Design, Quality,
  Reliability, Series and Signals, and Visualize; FEATURES.md
  lists them all.
• Sample data for every analysis (File ▸ Open sample data).
• Projects (.acraft) that reopen every report exactly; import of CSV, TSV,
  JSON and spreadsheet workbooks; export to CSV, TSV, JSON and .xlsx.
• Rhai scripting, formula columns, recorded actions and the headless
  anovacraft-run runner.
• Quick Guide and Reference Manual built into the app (Help menu).
• Accuracy checked against the NIST Statistical Reference Datasets and other
  independent references (docs/validation.md).

Downloads: a universal macOS app (Apple silicon and Intel, macOS 11 or
later) and a 64-bit Windows app. Neither is code-signed yet; see
README.md for how to open them the first time.
