Module vsf_builder 

High-level builder for VSF files

Uses the Vec<Vec> pattern with stabilization loop to handle the chicken-and-egg problem of header size calculation.

Note: Every VSF file requires and automatically includes a BLAKE3 hash in the header for integrity verification. This is computed transparently during build(). No manual hashing required - just call builder.build() and you’re done!
