/**
 * Creates the ltree connection filter operator factory.
 *
 * Registers operators on the LTree scalar type (only ltree columns):
 *
 * - `isAncestorOf`   -- column <@ to_path(value): finds descendants
 * - `isDescendantOf` -- column @> to_path(value): finds ancestors
 * - `matchesGlob`    -- column ~ to_query(value): glob/lquery pattern matching
 *
 * All operators accept dot-delimited paths or slash-delimited paths.
 * When ltree_helpers is installed, conversion happens server-side via
 * to_path() / to_query(). Otherwise, inline SQL casts are used.
