fix: resolve Copybara build regressions in S-Core

[Chahult]

• Replace invalid repo name '@safe_posix_platform@score_baselibs' with '@score_baselibs' in 6 BUILD load statements
• Fix tracing_library flag in .bazelrc from bare 'stub' label (resolves to non-existent //stub:stub) to proper label @score_baselibs//score/analysis/tracing/generic_trace_library/stub_implementation
