Cut pre-releases from a "next" branch

Enters changeset pre mode with the "rc" tag and lets the release workflow
run on this branch, so 2.0.0-rc.N can be published under the "rc" dist tag
while main keeps releasing stable versions. Pre mode is repo-wide state
(.changeset/pre.json lists every package), which is why it lives here
rather than on main.

Exit pre mode before merging this branch back into main.
