Toggle the process-wide "allow mutation on saved tensors" flag.
Used by lucid.autograd.graph.allow_mutation_on_saved_tensors to let
users opt into the unsafe contract that they will not mutate a saved
tensor in a way that would corrupt the gradient.
Parameters
vboolNew state of the override.
true disables version-counter checks; false re-enables them.Notes
The flag is global to the process — there is no per-thread or per-graph scoping. The Python context manager is responsible for restoring the previous value on exit.
