v0.2.0

[0.2.0] - 2026-08-12

Added

• A deterministic Gradle quickstart that generates a complete v13 EXTF file and verifies its whole-file SHA-256 during check.
• A permanent JMH benchmark module comparing retained and forward-only exporters.
• DatevCsv.requireExportable(...) for single-pass control-character and Windows-1252 validation.

Changed

• DatevStreamWriter now documents its forward-only write-through and caller-controlled buffering contract.
• Metadata application information now rejects non-Windows-1252 characters before output begins.
• Validation, schema lookup and CSV encoding paths allocate less while preserving validation behavior and emitted bytes.
