OR-002 Worker Registry and Discovery

Objective

Implement the worker registry and discovery contract for OminiX Runtime workers.

Scope

• Add a registry module to ominix-router-core or a sibling crate if transport code is required.
• Track worker endpoint, runtime namespace, model IDs, capabilities, health, and load.
• Support add, update, drain, offline, and remove.
• Define stale heartbeat behavior.

Acceptance Criteria

• Registry state transitions are covered by tests.
• Draining workers are visible but do not accept new requests.
• Offline workers are not routable.
• Registry output can feed the routing policy without translation loss.

Agent Notes

The registry must be ready for multiple runtime backends: OminiX CUDA, OminiX Ascend, and a temporary compatibility adapter.
