Cross-zone builtin programs are no longer registered in the production
genesis. A zone that participates declares the ones it uses via a new
GenesisAction::DeployProgram (sequencer) and a matching deploy_programs
list (indexer), both resolved through CrossZoneProgram and registered
with with_programs. Cross-zone genesis accounts (inbox config,
wrapped-token config) are seeded through the state constructor for a
receiving zone, and bridge-lock holdings are seeded from their actions
regardless of receiving config, dropping V03State::insert_genesis_account.
GenesisAction amounts now use the Balance alias. Documents cross_zone as
the reference LEZ adapter and the bridge demo as not production-safe.
The sequencer's DeployProgram set and the indexer's deploy_programs are
configured separately, so both nodes now log a deterministic genesis
fingerprint (V03State::genesis_fingerprint) at startup: equal values
confirm the two genesis states agree, a mismatch flags a divergent
deploy set.
BREAKING CHANGE: the genesis state root changes (cross-zone builtins are
out of production genesis) and the sequencer/indexer configs gain the
DeployProgram / deploy_programs list that cross-zone-participating zones
must set.
