fix(ci): clear duplicate declaration and retired-state assertion breaks

Two direct-landed changes left every PR red: release-candidate-checklist.d.mts
declared isDirectReleaseCandidateExecution twice with other declarations
between them (adjacent-overload-signatures), and the parallels smoke model
test still asserted the workspace-state.json seeding that b6535fb8de
deliberately retired. Drop the duplicate and flip the assertion to guard
the retirement.
