Extend deferred dispatch's destination pin to ordinary CLI fallback, so custom-root and active-profile changes cannot redirect a checked target. Refuse a missing destination before launch and name the target on failure. Replace the old env-clearing expectation with two behavioral invariants and retain the native Electron custom-root reproduction. Adapted from the root-boundary fix and diagnosis in #104066. Related #104055, #104066. Co-authored-by: fangliquanflq <fangliquan@qq.com>
