In `@Cargo.toml`:
- Around line 79-95: The NV28 migration was added but not wired into execution:
add a Height::NV28 variant to the Height enum and a NetworkVersion::V28 variant
to NetworkVersion, then register the nv28 migration module by inserting its
migration entry into each network's get_migrations() vector (at least for the
network(s) you intend to activate) so run_migration in src/state_migration::nv28
is actually invoked (remove the #[allow(unused)] once wired); also ensure an
actor bundle for the next actor version is published/registered so networks can
reach the new bundle version, or alternatively revert the fil_actor_* crate
version bumps back to the previous bundle until NV28 is fully integrated.
