Kept strict self-update prompt behavior while hardening the test suite for environments that cannot spawn child processes. The suite now gates integration-heavy checks behind a spawn capability probe and still enforces the prompt contract via source assertion fallback.

Constraint: CI/local environments may lack reliable child_process spawn support

Rejected: Drop self-update verification tests entirely when spawn fails | would hide regressions in prompt behavior

Confidence: high

Scope-risk: narrow

Reversibility: clean

Directive: Preserve the spawn probe + fallback assertion path when reshaping install.test.js bootstrap

Tested: npm test
