fix(ipc): one import of the incarnation module, not two

CI's code-quality plugins deny a second import of a module already imported in
the same file; the pre-commit hook runs a different oxlint config and did not
see it. Both failing checks were this: `verify` is a gate that only reported
static analysis, with typecheck, tests and both package jobs already green.
