Small Ollama models (qwen2.5:11b, qwen2.5:14b, similar) frequently emit
Pulse tool invocations as plain JSON inside content instead of routing
through the structured tool_calls channel. Users saw raw payloads like
`{"name": "pulse_query", "parameters": {...}}` as the assistant's final
response.
Extend cleanToolCallArtifacts and containsToolCallMarker with a new pass
that detects this leak shape, gated on a closed allowlist of canonical
tool names sourced from the runtime registry. The allowlist auto-syncs
when registerTools() gains a tool, so no separate hand-maintained list.
Anchored on (?:^|\n) and a leading `"name"` key so prose containing JSON
fragments, unrelated objects (`{"foo":"bar"}`), or named resources
(`{"name":"my-vm","cpu":50}`) are left untouched.
