/**
 * `graph-shard-worker <specPath>` — the per-shard build subprocess.
 *
 * One worker process builds ONE shard: it reads a {@link ShardWorkerSpec}
 * JSON file, runs parse → walk → resolve over the shard's explicit file
 * set (requesting cross-boundary descriptors), and writes a serializable
 * {@link ShardBuildResult} JSON to stdout. The parent (the shard runner)
 * spawns N of these under a concurrency cap and merges their fragments.
 *
 * This is an internal command, not a user-facing one — the shard runner
 * invokes `node <cliScript> graph-shard-worker <specPath>`. It exists as a
 * subcommand so the worker runs inside the bootstrapped CLI scope (the
 * language-adapter registry is populated), letting `pickAdapter` resolve
 * the adapter exactly as the main build does.
 *
 * The boundary is JSON only: no `ts.Node` / `ts.Program` ever crosses it.
