fix: use canonical _get_platform_tools resolver for memory tool status

The PR's inline toolset resolution (checking 'memory' in cli_toolsets
list) produced wrong results for composite toolsets like 'hermes-cli'
which expand to include the memory tool. Replace with the canonical
_get_platform_tools() from tools_config.py which correctly handles
composite toolsets and all edge cases.

Update tests to mock _get_platform_tools instead of raw config.
