/**
 * Layer 2 (v1.7.5): bundled-seed JSON loader.
 *
 * Reads `data/seed-models.json` (committed anchor; refreshed by
 * `scripts/build-seed.py` at release time) and exposes a typed Map for
 * O(1) lookups. Pure read; no DB; no fetch.
 *
 * **Schema v2** (current): three load-bearing fields per entry —
 * `maxTokens`, `queryPrefix`, `documentPrefix`. Everything else
 * (`dim`, `sizeBytes`, `prefixSource`, `modelType`, `baseModel`,
 * `hasDenseLayer`, `hasNormalize`, `runnableViaTransformersJs`) was dropped
 * because runtime probes `dim` from the loaded ONNX, and the rest is
 * informational. We also can't trust MTEB's curated `embed_dim` — verified
 * across the canonical presets, BAAI/bge-small-en-v1.5 has `embed_dim=512`
 * in MTEB but the actual model dim is 384.
 *
 * **Schema v1** (older anchors / pre-Python build script): superset shape
 * with all the cosmetic fields. Loaded transparently — the v1→v2 adapter
 * pulls the three fields we still care about and discards the rest.
 *
 * Bad shape / missing file → returns an empty map + writes a single stderr
 * warning. Resolver falls through to the live HF fetcher; we never crash.

 * a v1 anchor by mistake, or (b) ships an older committed seed via a

 * the back-compat branch genuinely tested rather than aspirational.
