pub fn register_discovery_tools(
registry: &mut ToolRegistry,
) -> Result<(), ErrorObject>Expand description
Register the read-only discovery tools (list_tools, describe_tool,
current_policy).
Ordering matters: discovery tools capture a snapshot of the registry’s
current capabilities. Always call this after every other capability has
been registered, otherwise the resulting list_tools() / describe_tool()
output will not include capabilities registered later.
