chore(deps): upgrade zerompk to 0.4 via patched fork with schema-evolution support

Pin zerompk and zerompk_derive to a fork that adds opt-in schema-evolution
attributes (`#[msgpack(default)]`, `skip_value`, mid-struct-default compile
guard), which are required for safe forward/backward-compatible catalog and
event-type serialization.
