fix: pass embedding kwargs (trust_remote_code) in preload_embedding()

[hurtdidit]

Bug

preload_embedding() in preload.py calls models.get_embedding_model() without forwarding the kwargs from the embedding config object. This causes HuggingFace models that require trust_remote_code=True (e.g., nomic-ai/nomic-bert-2048) to fail during startup preloading with:

Error in preload_embedding: nomic-ai/nomic-bert-2048 ... Please pass trust_remote_code=True

Root Cause

The config schema supports a kwargs field, and get_embedding_model() already accepts **kwargs and passes them through — but preload_embedding() never forwards them. The feature is half-implemented.

Fix

Extract kwargs from the config object with a safe default and forward them:

emb_kwargs = getattr(emb_cfg, "kwargs", {}) or {}
emb_mod = models.get_embedding_model("huggingface", emb_cfg.name, **emb_kwargs)

Two-line change to preload.py.

Impact

• Fully backward compatible — **{} is a no-op for configs without kwargs
• No config changes required
• Affects any HuggingFace embedding model requiring trust_remote_code (increasingly common)

Testing

Deployed and verified across 5 production Agent Zero instances (Docker). All instances show successful preload with All keys matched successfully and zero Error in preload_embedding messages.
