Migrating an httk v1 workflow to httk₂

For maintainers of an httk v1 workflow, moving it to httk₂ at whatever pace suits. An existing ht_steps/ht_run workflow can be kept unchanged in a converted package (language = "httk-v1"), migrated one job type at a time, or rewritten against the native APIs; finished v1 trees are harvested with httk workflow v1 collect. The central rule: migrate task definitions and newly instantiated task directories, never a live v1 task-manager queue.

The full guide, Migrating an httk v1 workflow to httk₂ in detail, walks through every step; httk v1 task compatibility describes the compatibility surface itself.
