Gergő Magyar	fca3494807	fix(embeddings): guard local ONNX runtime on macOS Intel before transformers.js import (#1987) ... * fix(embeddings): guard local ONNX runtime on macOS Intel before transformers.js import macOS Intel (darwin/x64) crashed on `gitnexus analyze --embeddings` with a raw `Cannot find module .../bin/napi-v6/darwin/x64/onnxruntime_binding.node`: both embedders imported @huggingface/transformers at module scope, which loads onnxruntime-node and resolves the (unshipped) native binding before any backend could be selected. ONNX_WEB_BACKEND=wasm could not help (#1516). - Add a native-free runtime-support guard (getLocalEmbeddingRuntimeBlocker) that returns a clear, actionable message on darwin/x64 and null elsewhere. - Convert both the core and MCP embedders to type-only transformers imports plus a guarded lazy `await import()`; throw the blocker in initEmbedder before any transformers.js / onnxruntime-node resolution. HTTP mode is unaffected. - Surface the blocker cleanly in the analyze CLI instead of the misleading "installation may be corrupt" module-not-found hint. - Add unit tests: guard DI, lazy-import timing, core+MCP darwin/x64 rejection, and HTTP mode not blocked.

The Embeddings section gains a "Support" line; on a blocked platform the full guidance (reused from getLocalEmbeddingRuntimeBlocker, single source of truth) is written to stderr. doctor stays import-safe — it never loads transformers.js or onnxruntime-node, so it runs cleanly on macOS Intel. Refs #1515 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(embeddings): close #1515 guard coverage gaps + PR #1987 review polish Resolves the maintainer tri-review feedback on PR #1987: - Add the analyze error-branch test (new analyze-local-embedding-error.test.ts): a darwin/x64 blocker routes to the clean local-embedding-unsupported message (exit 1), not the module-not-found "installation may be corrupt" branch, and wins over isHfDownloadFailure even when both match (guards the reorder below). - Cover the MCP embedQuery darwin/x64 paths — HTTP bypass via httpEmbedQuery without importing transformers, and local-mode rejection before the import. - Make the "defaults platform/arch" guard test falsifiable by stubbing the platform, instead of asserting null === null on the CI host. - analyze.ts: evaluate the blocker-message branch before the network-heuristic isHfDownloadFailure branch so the explicit platform message takes priority. - runtime-support.ts: the blocker message now also notes GITNEXUS_EMBEDDING_DEVICE =wasm/cpu cannot help, not only ONNX_WEB_BACKEND=wasm. - doctor.ts: resolve platform/arch once instead of re-resolving after the guard.
