Move branch-slug to @getpaseo/protocol

The app must not import @getpaseo/server. Moving the slug validation
and slugify helpers into @getpaseo/protocol (already a shared dep of
app, client, server) gives every package a legitimate home for the
import. Drops the corresponding ./utils/branch-slug subpath from
@getpaseo/server's exports map.

Unblocks the Deploy App workflow, which only builds protocol/client/
audio for the app — server's dist never exists in that pipeline.
