Mirrors the reusable tooling (scripts/, generic playbook templates,
.gitignore, conventions section of CLAUDE.md) into a new directory
and strips everything fleet-specific: servers/, stacks/, configs/,
fleet-named playbooks (deploy-*, decouple-*), runbooks, status,
host-pinned scripts.
Output is an empty conventionally-organized workspace with fresh git
history, ready to populate with a different fleet. Skeleton
CLAUDE.md / README.md / STATUS.md are written with the new fleet
name baked in but no server table or placement rules pre-populated.
Deliberately does NOT create a remote or push — the user picks the
namespace + name explicitly via tea / git remote add.
