What Audit Vcf Schema does

/audit-vcf-schema — Focused VCF FORMAT/INFO/FILTER drift check

Walk every `##FORMAT`, `##INFO`, and `##FILTER` line in `src/lancet/cli/vcf_header_builder.cpp` and verify that the bundle's claims about VCF schema match. This is the focused complement to `/audit-bundle` for the case where you want to check VCF schema specifically without running the full audit.

When to run this

After every release that touches VCF emission. After any change to `vcf_header_builder.cpp`, `variant_call.{h,cpp
