v0.1.2

What's new

PostgreSQL backend

• All 5 stores ported to asyncpg + pgvector (pip install memvee[postgres])
• Single db_url parameter — file path for SQLite, postgresql://... for Postgres
• Backend auto-detected from URL, or set explicitly via MemoryConfig(backend="postgres")
• HNSW vector index, tsvector/tsquery full-text search, connection pooling

Embedding adapters

• VoyageEmbedAdapter (memvee[voyage]) — voyage-3-lite, 1024 dims
• CohereEmbedAdapter (memvee[cohere]) — embed-v4.0, 1024 dims
• FastEmbedAdapter (memvee[local]) — BAAI/bge-small-en-v1.5, 384 dims, no API key
• Dimensions auto-detected from adapter — no need to set embedding_dimensions manually

Protocol cleanup

• Complete store protocols for all 5 stores + VectorIndex + TextIndex
• Backend factory in LifecycleManager — config-driven, lazy imports
• Retriever imports from protocols, not concrete storage

Breaking changes

• db_path renamed to db_url on Memory and MemoryConfig
• MemoryConfig.backend default changed from "sqlite" to "auto"

Docs

• Backend docs (SQLite + PostgreSQL setup)
• New monochrome + blue accent theme
• Copyedit pass across all docs
