Under the hood
Plugin and hook dispatch code adds a shared 'answering' tracking context around interface calls
What
The internal system that dispatches plugin and hook interactions now wraps its calls in a new "answering" tracking context, and the underlying press function now tracks whether each call is still active via a new liveness flag that clears once the call finishes.
Why
This is internal plumbing for tracking in-flight plugin/hook interactions; it's not described as changing anything a user would see directly.

Fixed the interactive /hooks menu crashing when a hook matcher is named after an inherited object property such as __proto__ or constructor
