Summary

• Fixes #463: Cannot resolve @huggingface/transformers before installing the onnxruntime pin shim on OpenCode nested Windows/npm cache installs.
• When Node createRequire(...).resolve fails, fall back to Bun.resolveSync and a filesystem walk of node_modules/@huggingface/transformers, then load the package's CJS export so the onnxruntime pin shim still applies.
• Clearer remediation in the error (clear plugin cache / use remote embeddings).

Test plan

• bun test tests/transformers-resolve.test.ts tests/runtime-require.test.ts tests/onnxruntime-resolve.test.ts
• bun run check
• On a Windows OpenCode install that previously hit Cannot resolve @huggingface/transformers before installing the onnxruntime pin shim. #463: clear ~/.cache/opencode/npm/opencode-mem@* (and packages cache), reinstall, confirm profile/list work again

Checklist

• Branch is based on main
• bun test passes (targeted)
• bun run typecheck passes
• bun run check passes

Closes #463
