Chroma requires client-side embeddings — the server is storage only.
The previous commit incorrectly removed @chroma-core/default-embed.
Uses DefaultEmbeddingFunction({ wasm: true }) which forces the WASM
backend instead of native ONNX binaries. Same model (all-MiniLM-L6-v2),
same embeddings, but works on all platforms without segfaults or
ENOENT errors (#1104, #1105, #1110).

/**

* ChromaSync Service
|
|
*
|
|
* Automatically syncs observations and session summaries to ChromaDB via HTTP.
|
|
* This service provides real-time semantic search capabilities by maintaining
|
|
* a vector database synchronized with SQLite.
|
|
*
|
|
* Uses the chromadb npm package's built-in ChromaClient for HTTP connections.
|
|
* Supports both local server (managed by ChromaServerManager) and remote/cloud
|
|
* servers for future claude-mem pro features.
|
|
*
|
|
* Design: Fail-fast with no fallbacks - if Chroma is unavailable, syncing fails.
