Shay 3620c967b9 fix: route production hot paths through algebra.backend (Commit 2)
Three surgical import changes. No behavior change. No new semantics.
Backend decides Rust vs pure-Python transparently.

- field/propagate.py: versor_apply <- algebra.backend
- vocab/manifold.py: cga_inner    <- algebra.backend
- vault/store.py:    recall loop replaced with vault_recall() from
  algebra.backend; public result shape preserved ({versor, score,
  metadata, index}). null_project stays on algebra.cga (not the
  recall hot path). store() and reproject() unchanged.

Rust path for vault_recall uses Rayon parallel scan and releases
the GIL. Python fallback is sequential and behaviorally identical.
No batching introduced; that is Commit 3+.

"""
VaultStore — exact memory via CGA inner product scan.
No HNSW. No approximate nearest neighbor. No index rebuild.
Recall is exact: argmax_i { cga_inner(query, X_i) } over stored versors.
Periodic null_project() prevents floating-point null-cone drift in long sessions.
Hot path: recall() routes through algebra.backend.vault_recall(), which
dispatches to a Rayon parallel scan (releases GIL) when core_rs is available
and falls back to a sequential Python scan silently. Public result shape
is unchanged: list of {versor, score, metadata, index}.
null_project() remains on algebra.cga — it is not the recall hot path
and does not benefit from the same batching pattern.
