Expose data descriptors for metadata and lazy argument arrays, preserve native title and parent PID behavior, and route native argument readers through the public properties. Ports the argv portion of oven-sh#44356 and metadata attributes from oven-sh#34229.
Exercise readonly writes with a strict Function constructor and native argv readers from a script rather than eval, preserving the Node 24 oracle assertions.

Suggested reviewers: Priority: ➖ Normal Merge Risk: 🔵 Low · up to The process behavior has no established blocking defect, but the new descriptor tests add avoidable serial startup time. The change is mergeable with that test improvement as a follow-up. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The change improves compatibility and adds validation where argument values enter native inspection code. No introduced security vulnerability was established. Risk remains low rather than minimal because initialization-failure recovery and externally reachable inspection configurations were not fully verified.

Run the descriptor tests concurrently.
Each matrix case and the native-setter test mutate only their own child process. The exitCode test is read-only, and the file has no setup or teardown hooks. describe.concurrent can overlap the 13 child-process launches and reduce serial startup time.

This makes commonly overridden process properties expose Node-compatible data descriptors, fixing descriptor-preserving replacements such as:
argvandexecArgvbecome lazy data properties. Native argument readers consult the public property instead of a separate cache, so replacements and throwing getters are observed consistently. The inspector validates the replacement before treating it as an array.ppidandtitleretain their live native behavior through native data properties.platform,arch,version,versions,pid, andreleasegain Node's read-only flag and remain configurable.Ports the argv portion of #44356 and the relevant metadata attributes from #34229; thanks @robobun. Those PRs remain open. The environment-map changes from #44356 are outside this patch, and no WebKit change is required.
