Function dynamic_catalog 

pub fn dynamic_catalog(
    source_id: impl Into<String>,
) -> (CatalogWriter, CatalogReader)

Constructs a fresh dynamic tool catalog as a writer/reader pair.

The writer mutates the catalog; the reader implements ToolSource and is what gets handed to an Agent. Both sides share storage internally — callers see only sized, owned values. Modeled on tokio::sync::watch::channel.

source_id appears as the source field on every emitted ToolCatalogEvent.

use agentkit_tools_core::dynamic_catalog;

let (writer, reader) = dynamic_catalog("plugins");
assert_eq!(writer.source_id(), "plugins");
assert_eq!(reader.source_id(), "plugins");
