Crate dpp_plugin_traits 

Host/guest ABI contract for Odal Node sector plugins.

Plugins implement DppSectorPlugin and export the three entry points as extern "C" symbols. The host invokes them through the wasmtime component model or directly via the low-level ABI defined below.

The interface is intentionally no_std-friendly: no heap allocations are required from the host’s perspective. Data is passed as JSON strings over a shared-memory slice.

Versioning

Every plugin declares which ABI version and schema versions it supports via PluginCapabilities. The host uses this for compatibility checks before dispatching any calls.
