Workshop external directory (target) for record linkage examples

A messier external directory of the same UK workshops as workshop_register, the target table for cross-source linkage. Listings carry the realistic distortions a scrappy directory introduces, planted as labelled tiers (via gen_tier) so each exercises a specific joinery feature: slogan-stuffed supersets (exact containment), movers that changed postcode area (token blocking with global rarity), phonetic name variants (Cologne/Soundex encoders), shared-venue and bare-category rows that bait over-linking (the containment guards), and common-surname homonyms (ambiguity and calibration). The matchable columns share names with workshop_register so one formula serves both tables.

Usage
