Add V8 crash information to crashReporter

Editor assessment

The subject is clear, V8 crash information is now attached to crashReporter output, but the type choice is questionable: adding a diagnostic capability reads as a feature, and the body's first squash bullet even labels it feat before the header settles on chore. The body otherwise lists review feedback handling, adding process detail but no rationale about what the crash data enables or why it matters for debugging. No scope, no footers, clean hygiene. Understandable, yet the internal inconsistency and absent motivation keep the message at acceptable.
