Subject: [PATCH] fix(tools): use _INTERNAL_BASE in serve-session endpoint
 registration (#3675)

#3322 renamed the loopback base to _INTERNAL_BASE, but a later Cookbook
commit reintroduced one call site using the old _COOKBOOK_BASE name,
raising NameError whenever the agent registers a model endpoint for a
running serve session.

Fixes #3669
