CONF-012: tools/list returns tools in a deterministic order

Severity	Applies to	Spec section
warn	modern era, stdio, http	2026-07-28/server/tools#capabilities

Calls tools/list three times and compares the order of tool names. Servers SHOULD return tools in the same order while the set is unchanged. Only the first page is compared.

From the command line: mcpprobe checks explain CONF-012. To leave it out of a run, add "CONF-012" to [checks] disable in mcpprobe.toml; to change how much it counts, use severity_overrides.
