Summary

• add an Examples section to the README with six workflow recipes
• cover patterns not in the docs: CI data-quality gate, ranking correlations by p-value, building a transform pipeline from skew_report, interpreting PCA via both calls, dropping collinear columns from a vif list, and a month-over-month KPI table
• links to the documentation site remain in place

Test plan

• review README diff
• confirm each recipe imports from percentify and runs end-to-end on a tiny inline DataFrame
• confirm no recipe duplicates a per-function example already in the docs
