- menu.ts: ReturnType → InstanceType for Separator class (fixes tsc error) - Remove @types/inquirer (inquirer v12 ships built-in types) - executor_concurrent_test.go: add --dangerously-bypass-approvals-and-sandbox to expected args - main_test.go: update version assertion 5.6.0 → 5.7.2 - ci.yml: restore typecheck + Go test steps (all passing now)
