/**
 * The tables the database browser lists, each with its columns in their
 * declared order, in one statement: `pragma_table_list` finds the tables
 * and `pragma_table_info` reads each one's columns, the pragma taking the
 * table name as an argument the way a table-valued function does.
 *
 * Left out: SQLite's own `sqlite_*` tables, and the shadow tables a
 * virtual table keeps its internals in (the `bot_file_vectors_*` tables
 * behind the sqlite-vec index), which are storage, not rows anyone
 * browses.
