Summary

adds a standalone showcase for score_baselibs, which was the only integrated module in known_good.json without one, and adds an ITF test for it in platform_integration_tests.

Changes

Showcase

• showcases/standalone/baselibs.score.json: new file with three examples:
  • Baselibs Builtin Logger Example: log_builtin sets up the built-in stdout logger and logs at every level, with a per-message context override.
  • Baselibs Custom Logger Example: log_custom installs a custom global logger and filters messages by level.
  • Baselibs C++ Logger Init Example: log_cpp_init sets up the logger from C++ and logs from Rust code.
• showcases/standalone/BUILD: new baselibs score_pkg_bundle that packages the three example binaries from @score_baselibs//examples.
• showcases/BUILD: registers baselibs_pkg_files in both the showcases bundle and the showcases_bundle filegroup (used for the QNX IFS).

Platform integration test

• platform_integration_tests/baselibs/BUILD: new py_itf_test, built the same way as the existing tests (Docker on linux_x86_64, QEMU on qnx_x86_64).
• platform_integration_tests/baselibs/test_baselibs_showcase.py: runs all three examples through the showcase CLI and checks that each one finishes successfully.
• platform_integration_tests/BUILD: adds the new test to the pit suite.

baselibs patch

• patches/baselibs/003-make-log-examples-visible.patch: makes //examples/log_builtin:log_builtin and //examples/log_custom:log_custompublic. Without it the bundle fails with a Bazel visibility error, because neither target setsvisibility. (log_cpp_init` is already public.)
• known_good.json: adds the patch to score_baselibs.bazel_patches.
• bazel_common/score_modules_target_sw.MODULE.bazel: regenerated with scripts/known_good/update_module_from_known_good.py.

This patch is a temporary workaround. Upstream to be fixed.
Once that is merged and the baselibs pin moves forward, patch 003 can be removed.

Testing

• bazel build //showcases/... on linux_x86_64
• bazel build //showcases/... on qnx_x86_64
• bazel test //platform_integration_tests/baselibs on linux_x86_64
• bazel test //platform_integration_tests/baselibs on qnx_x86_64
• Ran the showcases manually with the CLI: /showcases/bin/cli --examples=...

Open points

• Requirement traceability: the test uses partially_verifies=["<stkh_req id>"].
  Reviewers, please confirm the right baselibs stakeholder requirement.
