v0.4.1

Fix: explicit Ollama provider ignored the configured model

When BETTERDB_SUMMARIZE_PROVIDER=ollama (or BETTERDB_EMBED_PROVIDER=ollama) was set, the explicit-provider path hardcoded PRESET_CLEAN and ignored BETTERDB_SUMMARIZE_MODEL / BETTERDB_EMBED_MODEL. Users on a non-default Ollama model (e.g. qwen2.5:3b) were silently routed to mistral:7b; if that model wasn't pulled, createModelClient() threw and the Stop hook captured zero memories.

Both explicit ollama branches now build the preset from config.ollama.*, so the configured model and embedding dimension are honored.

Recommended: reinstall to rebuild your hook binaries (bunx @betterdb/memory install).
