Versions track the phases in the plan: a phase is released once its exit
criterion is met, not when its code lands. That keeps "released" meaning
something — v0.1.0 ships sim-engine and the routing libraries, and says plainly
that the gateway does not serve traffic yet.
scripts/gitea/milestones.py creates the matching Gitea milestones. Idempotent
and never destructive, so it can be re-run after the roadmap shifts.
