* fix(gateway): keep command-list field clamping UTF-16 safe
clampString truncated command names, descriptions, aliases, arg names/descriptions, and choice values/labels with a raw value.slice(0, maxLength). When an emoji (or other astral code point) straddles the clamp limit, the raw slice keeps a dangling high surrogate and emits a lone surrogate over the gateway commands.list protocol result. Route the clamp through the shared truncateUtf16Safe primitive so the boundary code point is dropped whole. Adds a regression test through buildCommandsListResult.
* test(gateway): fold UTF-16 clamp regression into bounds coverage
