Re-export the rs-matter crate A macro to generate the clusters’ meta-data for an endpoint.

Net-type tokens (pick exactly one):

• sys; - all system model clusters except the concrete Network Diagnostics cluster. Usually you want eth; / wifi; / thread; instead.
• eth; / wifi; / thread; - same as sys; plus the matching Network Diagnostics cluster.

Optional cluster-shape modifiers — supply zero or more, in the order shown, after the net-type token:

• sw_diag(heap | watermarks | thread, …) - shape the Software Diagnostics cluster’s advertised attribute/command surface. Tokens map to crate::dm::clusters::sw_diag::Options: heap → HEAP, watermarks → WATERMARKS (claims the Matter WATERMARKS feature and implies HEAP), thread → THREAD (advertises ThreadMetrics; unrelated to the Thread network protocol).
• time_sync(time_zone | ntp_client | ntp_server | time_sync_client, …) - shape the Time Synchronization cluster. Tokens map 1:1 to crate::dm::clusters::time_sync::Options and to the matching Matter features (TIME_ZONE, NTP_CLIENT, NTP_SERVER, TIME_SYNC_CLIENT).

Omitting a modifier advertises the corresponding cluster’s empty-options shape (required globals + always-on attributes, no features, no commands).

Trailing positional arguments are additional Cluster<'static> literals merged into the slice — e.g. clusters!(eth, sw_diag(heap); my_cluster).

The Groups cluster is intentionally not included in any of these presets: Root Node (Matter Device Library) does not list Groups, and Groups (Matter Application Cluster Specification) is scoped to per-endpoint group membership which has no defined behavior on the Root Node. Wire GroupsHandler::CLUSTER onto the application endpoint(s) where it actually has meaning instead.
