/**
 * Top-level .gg parser (v2, command-first grammar):
 *
 *   1. tokenize()        — character-stream → Token[] (dsl.ts)
 *   2. parseStatements() — Token[] → per-statement results (dsl.ts)
 *   3. fold into DiagramDef — merge `doc` bodies (deep-merge, later wins)
 *      and accumulate icon / region / note / connector arrays.
 *   4. checkIntegrity()  — duplicate ids, valid refs, region connectedness.
 *
 * No more `%%{…}%%` directives — all scalars / theme / icons come from
 * `doc { … }` statements.
