Rename task/ to tasks/ and update all references

- Renamed task/task.yaml to tasks/tasks.yaml for consistency
- Updated README.md references from task/task.yaml to tasks/tasks.yaml
- Updated directory structure documentation from task/ to tasks/
- Updated tasks/README.md to reference correct filename
- Fixed various linting issues in test files
- All tests still pass (78/78)
