fix(skills): point the orchestration error contract at its moved module

#6150 branched before #6134, so skill-lifecycle.ts imports
@/lib/workflows/orchestration/types — the module #6134 moved to
@/lib/core/orchestration/types. Git merged a file deletion on one side with a
new file referencing it on the other: no textual conflict, broken build.
