example.javalib.__.native.server.test CI job doesn't seem to be benefiting from selective testing

[lihaoyi]

Every other job seems to benefit, we need to investigate and figure out why this one does not

Here's the selective.resolveTree:

Not sure why dist.native.executableRaw is triggering selective execution of downstream tests, but that at least explains why it only happens for the .native version of the tests and not .packaged or .local

[lihaoyi]

The new selective.resolveChanged command has confirmed that dist.native.executableRaw is the invalidation root. The question remains why it can be one when neither the code nor the build config has changed

[lihaoyi]

Seems to be specific to our multi-stage CI process with separate build and test jobs; doesn't happen when the selective execution logic is run on a single machine https://github.com/com-lihaoyi/mill/actions/runs/12839331167/job/35806439311?pr=4357
