Closes#678.
BREAKING CHANGE: `wrapped_token` and `bridge_lock` image ids move, relocating the
wrapped-token config and every holding PDA. A lock above the cap is now refused
at the source rather than escrowing balance the destination will not mint.
Closes#676.
BREAKING CHANGE: the seen-shard PDA address and its data layout both change, so
every message delivered under the old layout becomes deliverable again at the new
address, and the old shards are orphaned. A fresh genesis is required.
BREAKING CHANGE: `CrossZoneMessage` gains `src_block_hash`, changing the risc0
encoding of `cross_zone_inbox::Instruction::Dispatch` and the inbox image id,
and with it the inbox config and seen-shard PDA addresses. A pending dispatch
record written by earlier code no longer names a registered program, so it fails
production and is dead-lettered rather than delivered. Drain the pending list
before upgrading, or accept that in-flight deliveries are lost.
BREAKING CHANGE: `CrossZonePeer.allowed_targets` is replaced by `allowed_routes`,
a list of `{src_program_id, target_program_id}` pairs. `InboxConfig.allowed_peers`
is removed.
Integrates origin/main (per-program-crate refactor) and re-homes the cross-zone messaging feature onto it.
BREAKING CHANGE: Genesis state root changes. This registers six builtin programs
(cross_zone_outbox, cross_zone_inbox, ping_sender, ping_receiver, bridge_lock,
wrapped_token) and seeds their genesis accounts (the wrapped_token authorized
minter config, the per-zone inbox config, and optional bridge-lock holdings).
Building the new cores alongside the existing builtins also enables serde/alloc
for the shared programs build, regenerating every builtin program image id. All
nodes must upgrade together.
