Remote tool-call requests can now include a read_baseline field

What

The internal message format used for remote/cloud tool-call requests (part of the remote-control protocol) now accepts a readBaseline value, which gets sent out as read_baseline in the request, but only when no approval has been given yet.

Why

This is an internal protocol addition for how Claude Code communicates with remote or cloud-connected sessions; it does not change anything a user directly interacts with.
