Address ndgrigorian review: remove tensor-specific references

- dpctl/tests/AGENTS.md: focus on SYCL objects and memory APIs, remove dtype/USM lists
- .github/instructions/testing.instructions.md: drop tensor-specific coverage rules
- dpctl/utils/AGENTS.md: remove get_execution_queue() (removed in tensor migration)
- AGENTS.md: update directory descriptions
- dpctl.instructions.md: clarify queue consistency for memory ops

Feedback addressed: tensor module removed, documentation updated accordingly.

-
-### get_execution_queue()
-Validates queue compatibility between arrays:
-```python
-from dpctl.utils import get_execution_queue
-
-exec_q = get_execution_queue([x.sycl_queue, y.sycl_queue])
-if exec_q is None:
-    raise ExecutionPlacementError("Incompatible queues")
-```
-
-### ExecutionPlacementError
-Exception raised when arrays are on incompatible queues.
-
-## Notes
-
-- `get_execution_queue()` is critical for all tensor operations
-- See usage examples in `dpctl/tensor/` modules
