Resolves the Windows symlink breakage from
bazelbuild/bazel-central-registry#5490 by replacing
examples/crossbuild/protobuf.patch with a full copy. Bumps rules_python
to 1.5.2 for both Bzlmod and legacy WORKSPACE builds.

---

This is hopefully a temporary measure to unblock the next `rules_scala`
release. This will probably require creating a v7.1.1 tag to trigger a
new .bcr/presubmit.yml workflow.

See bazelbuild/bazel-central-registry#5506 for details about the
breakage. If and when bazelbuild/continuous-integration#2350 lands and
makes its way to the BCR presubmit build, we could restore the symlink.
Better yet, if protocolbuffers/protobuf#19679 ever lands, we could
remove this symlink and all the others.

Bumped `rules_python` to 1.5.2 for legacy `WORKSPACE` builds because it
contains bazel-contrib/rules_python#3134, which fixes
bazel-contrib/rules_python#3119.

@meteorcloudy Mind trying to re-run this one, too, seeing that bazelbuild/continuous-integration#2350 fixed #5205?

Done, but looks like there is some other failure on windows, maybe you'll need to add --enable_runfiles (or use the runfiles library in some tool)?

Hmm, crap...our Windows builds didn't catch whatever this is. Will look into it, thanks!

Fixes the runfiles problems with Windows builds for Bazel 8 and later
seen in bazelbuild/bazel-central-registry#5490. Bumps a number of
dependencies, and bumps the `rules_scala` version in `MODULE.bazel` from
`7.1.0` to `7.1.1`.

Dependency version bumps include:

- Go: 1.24.5 => 1.25.0
- `golang.org/x/tools`: v0.35.0 => v0.36.0
- `jline`: 3.30.4 => 3.30.5
- `protobuf-java`: 4.31.1 => 4.32.0
- `protobuf`: v31.1 => v32.0
- `rules_java`: 8.15.0 => 8.15.1
- `rules_python`: 1.5.2 => 1.5.3

Also:

- Restores `examples/crossbuild/protobuf.patch` to a symlink, undoing
  the change from bazel-contrib#1760.

- Fixes precompiled Windows protoc selection on ARM64 in
  `protoc/private/protoc_toolchains.bzl`.

- Removes `RULES_SCALA_MAIN_WS_NAME` from the ScalaTest runner
  implementation.

- Removes `rules_jvm_external` from `scala/latest_deps.bzl`.

bazelbuild/continuous-integration#2350 resolved the Windows symlink
problem, fixing the bazelbuild/bazel-central-registry#5490 Bazel 7
Windows build. This enables the restoration of the original
`examples/crossbuild/protobuf.patch` symlink, effectively closing
bazelbuild/bazel-central-registry#5506.

The `src/java/io/bazel/rulesscala/exe/LauncherFileWriter.java` changes
fix the remaining bazelbuild/bazel-central-registry#5490 breakages.
Specifically, adding the `.exe` suffix only when necessary under Bazel 7
fixes the Windows builds for Bazel 8 and later. However, we'll have to
close that pull request and push the v7.1.1 tag to begin a new release.

The updates to use `@AutoBazelRepository` and `Runfiles.preload()`, etc.
are from the `com.google.devtools.build.Runfiles` docstring:

- https://github.com/bazelbuild/rules_java/blob/8.15.1/java/runfiles/src/main/java/com/google/devtools/build/runfiles/Runfiles.java#L31-L134

`RULES_SCALA_MAIN_WS_NAME` is no longer necessary given proper runfiles
library usage, and technically became obsolete in commit
f758956.

Instantiating `rules_jvm_external` ourselves is no longer necessary
because `protobuf` v32.0 contains protocolbuffers/protobuf#22225, which
closed protocolbuffers/protobuf#19129.

I've tested this change using my personal Windows 11 ARM64 virtual
machine, hence the updates to `protoc/private/protoc_toolchains.bzl`.
Previously, the `exec_compatible_with` attribute of the toolchain target
contained `@platforms//cpu:x86_64` instead of `@platforms//cpu:aarch64`.
This caused `@protobuf//bazel/private:proto_toolchain_type` to resolve
to `@protobuf//bazel/private/toolchains:protoc_sources`, triggering
recompilation.

I also had to use `python.single_version_platform_override` and to fix
`@bazel_tools//tools/jdk:proguard_whitelister` on Windows ARM64. This is
because the latest `rules_python` 1.5.3 doesn't contain any entries for
`aarch64-pc-windows-msvc` in `//python:versions.bzl`.

However, it appears such entries are coming in the next `rules_python`
release, which will eliminate the need for such a workaround. For that
reason, I haven't tried to include it in this change.

Fixes the runfiles problems with Windows builds for Bazel 8 and later
seen in bazelbuild/bazel-central-registry#5490. Bumps a number of
dependencies, and bumps the `rules_scala` version in `MODULE.bazel` from
`7.1.0` to `7.1.1`.

Dependency version bumps include:

- Go: 1.24.5 => 1.25.0
- `golang.org/x/tools`: v0.35.0 => v0.36.0
- `jline`: 3.30.4 => 3.30.5
- `protobuf-java`: 4.31.1 => 4.32.0
- `protobuf`: v31.1 => v32.0
- `rules_java`: 8.15.0 => 8.15.1
- `rules_python`: 1.5.2 => 1.5.3

Also:

- Restores `examples/crossbuild/protobuf.patch` to a symlink, undoing
  the change from #1760.

- Fixes precompiled Windows protoc selection on ARM64 in
  `protoc/private/protoc_toolchains.bzl`.

- Removes `RULES_SCALA_MAIN_WS_NAME` from the ScalaTest runner
  implementation.

- Removes `rules_jvm_external` from `scala/latest_deps.bzl`.

---

bazelbuild/continuous-integration#2350 resolved the Windows symlink
problem, fixing the bazelbuild/bazel-central-registry#5490 Bazel 7
Windows build. This enables the restoration of the original
`examples/crossbuild/protobuf.patch` symlink, effectively closing
bazelbuild/bazel-central-registry#5506.

The `src/java/io/bazel/rulesscala/exe/LauncherFileWriter.java` changes
fix the remaining bazelbuild/bazel-central-registry#5490 breakages.
Specifically, adding the `.exe` suffix only when necessary under Bazel 7
fixes the Windows builds for Bazel 8 and later. However, we'll have to
close that pull request and push the v7.1.1 tag to begin a new release.

The updates to use `@AutoBazelRepository` and `Runfiles.preload()`, etc.
are from the `com.google.devtools.build.Runfiles` docstring:

- https://github.com/bazelbuild/rules_java/blob/8.15.1/java/runfiles/src/main/java/com/google/devtools/build/runfiles/Runfiles.java#L31-L134

`RULES_SCALA_MAIN_WS_NAME` is no longer necessary given proper runfiles
library usage, and technically became obsolete in commit
f758956.

Instantiating `rules_jvm_external` ourselves is no longer necessary
because `protobuf` v32.0 contains protocolbuffers/protobuf#22225, which
closed protocolbuffers/protobuf#19129.

I've tested this change using my personal Windows 11 ARM64 virtual
machine, hence the updates to `protoc/private/protoc_toolchains.bzl`.
Previously, the `exec_compatible_with` attribute of the toolchain target
contained `@platforms//cpu:x86_64` instead of `@platforms//cpu:aarch64`.
This caused `@protobuf//bazel/private:proto_toolchain_type` to resolve
to `@protobuf//bazel/private/toolchains:protoc_sources`, triggering
recompilation.

I also had to use `python.single_version_platform_override` and to fix
`@bazel_tools//tools/jdk:proguard_whitelister` on Windows ARM64. This is
because the latest `rules_python` 1.5.3 doesn't contain any entries for
`aarch64-pc-windows-msvc` in `//python:versions.bzl`.

However, it appears such entries are coming in the next `rules_python`
release, which will eliminate the need for such a workaround. For that
reason, I haven't tried to include it in this change.

Can this be rerun given all the upstream changes in rules_scala or do they need to cut a new release to have it go smoothly?

@FrankPortman I pinged @simuons in bazel-contrib/rules_scala#1761 (comment) to please push a v7.1.1 tag. I don't think there's a way for this PR to pick up the changes.

@meteorcloudy Now that #5673 successfully published rules_scala v7.1.1, could you please close this pull request?

Adds a matrixed `bcr_presubmit` job to `.bazelci/presubmit.yml` to
parallel `.bcr/presubmit.yml`. Bumps the `MODULE.bazel` version to 7.1.2
and updates a number of Bazel module and Maven artifact dependencies.

- `com.thesamet.scalapb`: 1.0.0-alpha.1 => 1.0.0-alpha.2
- `io.grpc`: 1.74.0 => 1.75.0
- `org.scala-sbt:util-interface`: 1.11.4 => 1.11.5
- `proto-google-common-protos`: 2.60.0 => 2.61.0
- `rules_cc`: 0.1.4 => 0.2.3
- `rules_go`: 0.56.1 => 0.57.0
- `rules_java`: 8.15.1 => 8.15.2
- `rules_python`: 1.5.3 => 1.6.0-rc2
- `rules_shell`: 0.5.1 => 0.6.0

Also contains minor updates to `test_dependency_versions.sh`.

---

The matrixed `bcr_presubmit` job should prevent future failed Bazel
Central Registry releases like bazelbuild/bazel-central-registry#5490
for 7.1.0. If the CI job passes, particularly the daily build job, then
the BCR release pull request should pass.

The `MODULE.bazel` version bump to 7.1.2 prepares us for the next
release. All the version updates other than `rules_python` are routine
updates.

The `rules_python` version bump to 1.6.0-rc2 contains
aarch64-pc-windows-msvc build support. This enables `rules_scala`
building, testing, and debugging on the Windows Arm64 platform without
using `python.single_version_platform_override`. See:

- bazel-contrib/rules_python#2276 (comment)

The `test_dependency_versions.sh` updates include:

- resolvng a silent `cp` failure on `deps/test/*.{scala,bzl}`
- invoking `set -e` earlier to catch such failures
- reorganizing logic for readability
- improving the `do_build_and_test()` function comment
