Full module path rebrand from Temporal to Hanzo Tasks: - go.mod module: github.com/hanzoai/tasks - All internal Go imports updated (1906 files) - cmd/server renamed to cmd/tasksd - Binary name: tasksd (was temporal-server) - Docker images: hanzoai/tasks (was temporalio/server) - README rewritten with Hanzo Tasks branding - LLM.md created with integration notes - Makefile, goreleaser, CI workflows updated - go.temporal.io/sdk and go.temporal.io/api imports preserved (separate repos) Fork of Temporal.io (MIT license).
