### Fixes

- Control UI/Gateway: preserve WebChat client version labels across localhost, 127.0.0.1, and IPv6 loopback aliases on the same port, avoiding misleading `vcontrol-ui` connection logs while investigating duplicate-message reports. Refs #72753 and #72742. Thanks @LumenFromTheFuture and @allesgutefy.

- Memory-core: run one-shot memory CLI commands through transient builtin and QMD managers so `memory index`, `memory status --index`, and `memory search` no longer start long-lived file watchers that can hit macOS `EMFILE` limits. Fixes #59101; carries forward #49851. Thanks @mbear469210-coder and @maoyuanxue.

- Memory-core: re-resolve the active runtime config whenever `memory_search` or `memory_get` executes, so provider changes made by `config.patch` stop leaving stale embedding backends behind in existing tool instances. Fixes #61098. Thanks @BradGroux and @Linux2010.

- WebChat: keep bare `/new` and `/reset` startup instructions out of visible chat history while preserving `/reset <note>` as user-visible transcript text. Fixes #72369. Thanks @collynes and @haishmg.
