* perf: build graph for next batch in parallel to keep GPU busy

This refactors the main run loop of the ollama runner to perform the main GPU
intensive tasks (Compute+Floats) in a go routine so we can prepare the next
batch in parallel to reduce the amount of time the GPU stalls waiting for the
next batch of work.

* tests: tune integration tests for ollama engine

This tunes the integration tests to focus more on models supported
by the new engine.

Add some new test coverage for various model architectures,
and switch from orca-mini to the small llama model.

Both interface{} and any (which is just an alias for interface{} introduced in Go 1.18) represent the empty interface that all types satisfy.

This had fallen out of sync with the envconfig behavior, where max queue default was not zero.

This test needs to be able to adjust the queue size down from
our default setting for a reliable test, so it needs to skip on
remote test execution mode.
