Export dynamic plugin entry points with FFI vtables.

Generates:

• drasi_plugin_metadata() → version info for validation
• drasi_plugin_init() → FfiPluginRegistration with vtable factories
• Plugin-local tokio runtime, FfiLogger, lifecycle callbacks

Usage

drasi_plugin_sdk::export_plugin!(
    plugin_id = "postgres",
    core_version = "0.1.0",
    lib_version = "0.3.8",
    plugin_version = "1.0.0",
    source_descriptors = [PostgresSourceDescriptor],
    reaction_descriptors = [],
    bootstrap_descriptors = [PostgresBootstrapDescriptor],
);

An optional worker_threads parameter sets the default number of tokio worker threads for the plugin’s runtime (default: 2). This can be overridden at deploy time via the DRASI_PLUGIN_WORKERS environment variable.

drasi_plugin_sdk::export_plugin!(
    plugin_id = "postgres",
    // ...
    bootstrap_descriptors = [PostgresBootstrapDescriptor],
    worker_threads = 4,
);
