The compiled binary embeds onnxruntime_binding.node but not its transitive dependency libonnxruntime.1.21.0.dylib, causing semantic search to silently fall back to FTS-only. Fix by switching to the WASM backend (onnxruntime-web) at build time: - Build script stubs onnxruntime-node with onnxruntime-web re-export during compilation, then restores the real package afterward - Embedder configures writable cache dirs (models + WASM runtime) to avoid /$bunfs read-only filesystem in compiled binaries - WASM runtime files are downloaded once from CDN on first run and cached in ~/.cache/pramana/wasm/ - Add onnxruntime-common as direct dependency to fix Bun package resolution - Tighten smoke test to assert no dlopen/libonnxruntime errors Closes #38 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
