lance's crates compile protos of their own and look for a protoc, so every job
that builds the worker failed at lance-encoding's build script. They read
PROTOC, so pointing it at the binary protoc-bin-vendored already puts in the
registry serves them without a system package - one less apt call on the way
to a release, and the same version everywhere.

Nothing built seaweed-worker in CI, so the release and the container images
would have been the first place a break showed up. Tests run in release too,
rather than compiling lance, arrow and datafusion again in another profile.
