Addresses #1974

Not ready to be merged yet: I find it does enable the use of PyTorch 2.7.1 (good!) but breaks the InstanSeg extension (bad!).

Reason seems... surprising.

We make calls to baseManager.debugDump(2). This attempts to create a substring of a UUID, which would be ok except that UUIDs aren't used any more.

The result is

java.lang.StringIndexOutOfBoundsException: Range [24, 21) out of bounds for length 21

We should be able to work around it by avoiding any use of debugDump - I've checked that removing this line means that InstanSeg can run. But I suspect this must affect others.
