zeekay 5a601d081b rebrand: go.temporal.io/server -> github.com/hanzoai/tasks
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)
