before

# bazel cquery --config=remote_config 'somepath(//some/nodejs_binary:target, @nodejs_darwin_arm64//:node_bin)'
//some/nodejs_binary:target (7160162)
@nodejs//:node_bin (7160162)
@nodejs_darwin_arm64//:node_bin (7160162)

after:

# bazel cquery --config=remote_config 'somepath(//some/nodejs_binary:target, @nodejs_darwin_arm64//:node_bin)'
INFO: Empty query results

That this fixes the issue likely points to some flaw in how Bazel 7 builds the repo mapping file.

Regardless of the reasons, this is a net positive change and one I am familiar with from my work in the overhaul branch. (lib/private/rules/nodejs_binary_test/attrs.bzl has no references to @nodejs)
