Add a structured business facts SQLite layer for Kingdee sales orders, with fixed-template query commands for monthly order counts, sales amount, top customers, and customer trend data.
Update README, SETUP, and developer docs to describe configuration, sync commands, query examples, and the boundary between structured facts and wiki ingest.
Validation: python3 -m unittest discover -v
Track the source-of-truth code, skills, bootstrap rules, docs, and packaging files before adding new features.
Exclude local vault config, generated skill mirrors, temporary exports, virtual environments, and business data files from version control.
Validation: inspected staged file list and git ignored status before commit.
