feat(P4-002): semantic search — pgvector embeddings + search API

Add EmbeddingService using OpenAI-compatible embeddings API (supports
text-embedding-3-small, configurable via EMBEDDING_MODEL and
EMBEDDING_API_URL env vars). Wire embedding generation into insight
creation and semantic search endpoint. POST /api/memory/search now
generates a query embedding and performs cosine distance search via
pgvector when OPENAI_API_KEY is configured.
