What
Hook entry points now receive an explicit session built from the session id, original working directory and project root, rather than reading ambient state. Covers ConfigChange, FileChanged, CwdChanged, Notification, DirectoryAdded, SessionEnd, StopFailure, WorktreeCreate and Remove, PreCompact and PostCompact, and Elicitation.
Evidence
hook_event_name: "CwdChanged"
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
