/**
 * Create a captioner for the requested visual-quality profile. Sets
 * `env.cacheDir` immediately so the global is correct even if the captioner
 * is constructed before any embedder initializes.
 *
 * Concurrency assumption: `env.cacheDir` is a process-global from
 * `@huggingface/transformers`. Setting it here at construction time is safe
 * for the current single-instance usage (one captioner per ingest run). If
 * the codebase ever constructs multiple captioners with DIFFERENT `cacheDir`
 * values in parallel, the last writer wins and the first captioner's
 * `from_pretrained` may resolve against the wrong cache. Avoid concurrent
 * construction with differing cacheDirs.
