Module vector 

Vector subsystem.

This module is the in-process home of the Redis-Stack-style RediSearch FT.* command surface. The architecture decision lives in docs/dynvec/fold-into-redis-path.md; the short version is:

1. The dynvec crate provides the per-table storage + HNSW index engine.
2. This module wraps each registered index in a VectorTable and tracks them in a VectorRegistry.
3. The Redis parser recognises FT.* commands and routes them through this registry (Phase C, follow-up work).
4. Distributed k-NN queries are coordinated by the query_fsm state machine, which fans out to every primary peer covering the index’s key range and merges the per-peer top-K replies.

Phase B (this commit) lands the registry, the schema types, and the moved query coordinator. The FT.* command parser, the cluster-machinery integration in query_fsm, and the deprecation of the standalone [dynvec::api] HTTP surface are each follow-up work.
