Finally all Pro and Max user now get access to Claude Code Projects

Replaces the folder-style project with a coordinator that scopes a goal, hands pieces to parallel threads, reviews their output and assembles the finished result.

Each thread is a full Claude Code cloud session on its own branch and repo copy. Threads write to and read from one shared project memory, which allows decisions made in one task, like a moved release date, shape later tasks without re-prompting.

Also good collisions handling, e.g. collisions between threads resolve as normal merge conflicts rather than silent overwrites.

It was launched in beta on Sept-17, but only for a narrow group had access.
