/**
 * Draw-On-Graph Resolver
 *
 * Determines whether a project is DRAWN on the architecture graphs. Every
 * project is drawn by default; a project opts OUT by carrying the nx tag
 * `drawOnGraph:false` on its project.json. When hidden, the project (and every
 * edge touching it) is omitted from the rendered HTML/DOT of BOTH the
 * dependency graph (architecture/dependencies.html) and the runtime graph — but
 * the project stays in dependencies.json / runtime-dependencies.json with an
 * additive `"drawOnGraph": false` field, so the data view remains complete.
 *
 * Resolution order:
 * 1. Explicit nx tag `drawOnGraph:<true|false>` on the project (project.json
 *    tags). At most one, and the value must be exactly `true` or `false`.
 * 2. Fallback: `true` (drawn) — the safe default so an untagged project always
 *    appears on the graph.
