Agent Skills: data-dict

Reads a codebase and discovers its database schema wherever it is defined — Liquibase changelogs, raw SQL run through JDBC, and Hibernate/JPA entities — merges them into one model, and renders a self-contained light-theme website with three tabs (a per-table data dictionary, a hand-drawn ER diagram, and an in-browser SQL query console). Use when the user runs /data-dict or asks to document, map, visualize, or generate a data dictionary for a project's database schema.
