This new snapshot suite gates on isXcodeIdeBridgeAvailable() and then calls real xcode-ide tools (list-tools, call-tool DocumentationSearch) which exercise the actual xcrun mcpbridge and a running Xcode instance. Per the skill guardrails, unit tests must not call real xcrun/devices/simulators; this is acceptable here because it is a snapshot/integration suite (not a unit test) and is conditionally skipped when the bridge is unavailable, but reviewers should treat the resulting fixtures as contract changes requiring scrutiny.
