### Added



- Pure-Elixir parsing and canonical writing for VCF 4.1 through 4.5.

- Typed headers, records, fields, samples, and arbitrary-ploidy genotypes.

- Explicit version profiles with type, cardinality, allele, and phasing validation.

- Strict and permissive modes with machine-readable errors and warnings.

- Bounded-memory streams for paths, I/O devices, and one-shot enumerables.

- Sequential plain, gzip, and concatenated BGZF input plus gzip output.

- Stable metadata, INFO, FORMAT, sample, record, and alternate-allele ordering.

- Property, version-fixture, robustness, and million-record streaming coverage.
