ci(OpenClawKit): assert ElevenLabsKit drops when Talk trait disabled

Adds a macOS-lane guard so future sources under OpenClawKit cannot silently
reintroduce an unconditional ElevenLabsKit dependency while the manifest still
looks correct. Resolves the graph with --disable-default-traits, fails if
ElevenLabsKit appears, and builds the kit trait-off.

Addresses review feedback from @byungskers on the trait PR.
