Bump communication to 0e064099 and adapt integration

Update score_communication to 0e0640998096049a8dd65a4173b03a988d5a85a7
and pull in the cascading dependency and toolchain changes required by it.

Modules:
- score_communication -> 0e064099
- score_tooling -> 7099e272 (needs component(target_compatible_with))
- add lobster git_override, bump trlc -> 8d25f639 (required by new tooling)

Toolchain:
- add LLVM/libclang toolchain (toolchains_llvm 1.8.0, llvm 19.1.7) used by
  the score_tooling C++ parser for communication code generation
  (bazel_common/score_llvm_libclang.MODULE.bazel, bazel/toolchains/BUILD,
  registered via .bazelrc --extra_toolchains)

Flags:
- tracing library flag moved from communication into baselibs:
  .bazelrc now sets
  @score_baselibs//score/analysis/tracing/generic_trace_library:implementation

Patches:
- 001-expose-comm-examples: rewritten to export the new rust example config
- 003-module-deps-visibility: regenerated for the new MODULE.bazel
- 002-tests-visibility and 004-tracing-library-target: removed (obsolete)

Showcase:
- migrate standalone comm showcase from the removed C++ ipc_bridge example
  to the rust com-api-example (BUILD, com.score.json, itf test_showcases.py)
