feat: TruePVE in the zone step (PLAN_REDESIGNS §14.3.2, WIP)

Stage 3 of the §14.3 integration plan (D362, D368): world.zone's optional
truePve ({exclude: true} or {ruleset}), all or nothing, unmapped on every
path that erases one of our zones, with truepve.json for erases while
TruePVE is away. Docs and PRs still to come.
