Distinct ``tool_name`` values within the requested filter scope.

Powers the FE TraceHeader tool-filter dropdown. Without this endpoint,
the FE has to derive available tools from spans the user has manually
expanded — most users never expanded enough sessions to see the filter
populate. Returns a flat sorted list capped server-side.

Same filter precedence as ``/sessions`` (``agent_id`` wins; else
``(project_key_id, client_id)``; else fleet-wide). Default range is the
last 24h, matching the rollup window.
