feat(occ): ship board 3D model bodies with STEP/GLB exports (3d-models 0007)

The occ_service export worker has its own MEMFS — the editor's lazily-fetched
lib models were invisible there, so every export was a bare board (54
"Could not add 3D model" warnings on pic_programmer, 2 STEP products).

- models-bridge: collectBoardModelFiles(boardText) — scan refs, ensure via
  the 0004 sparse source (IDB/R2, wrl->step fallback), read staged bytes
  back, dedupe by real staged path.
- occ-service.ts: attach the collected models to every export request
  (best-effort — prefetch failure still exports, misses reported by the
  exporter); transfer the body buffers.
- occ-worker.js (shared app/harness): pass req.models through to occExport.
- occ_service_main.cpp: occExport(board, params, models) stages each entry
  under PCBJAM_3D::MODELS_MEMFS_ROOT (path-sanitized) for the exporter's
  staged-model probe (kicad 83645275ac), removed again after the export.
- tests: harness occ stub mirrors the prefetch against the page kicadLibs
  provider + captures report/productCount; new occ-export-models.spec.ts
  guards the delivery (green companion pins preconditions; guard asserts 0
  missing lib models + component PRODUCTs). pic_programmer: 17/17 staged,
  87 products @ 13.3 MB (was 2 @ 402 KB). models-bridge unit tests 13/13.

Known remainder (0007 step 4): project-local ${KIPRJMOD} refs still drop.

/**
* STEP export × 3D model delivery (docs/features/3d-models, 0007): File →
* Export → STEP must include the board's lib component models.
*
* The STEP export runs in the occ_service worker — its own wasm module with
* its own MEMFS, where the editor's model files are invisible. Delivery
* (0007): the export request ships the board's prefetched lib model bodies
* (`models` array — in the app collected via models-bridge from R2/IDB; here
* mirrored by the harness occ stub against the page's kicadLibs provider),
* the worker stages them under /pcbjam/3dmodels, and EXPORTER_STEP's
* staged-model probe (pcbjam_model_fetch.h FindStagedModel) resolves them on
* a resolver miss.
*
* The first test pins the preconditions (board really references lib models,
* the export chain itself works, the model provider serves any ref) so a
* failure of the second can only come from the delivery, not the harness.
