Module vector_ref 

Zero-copy vector reference abstraction.

This module provides the VectorRef trait for zero-copy access to vectors, eliminating heap allocations during search operations.

Performance

Using VectorRef instead of Vec<f32> eliminates:

• Heap allocations: 0 allocations per read vs ~10k for 10k vector search
• Memory copies: Direct slice access from mmap
• Allocator pressure: No fragmentation from repeated alloc/dealloc

Structs
