Acceptance Criteria:\n- web.search proxies Ollama Cloud's /api/web_search via the configured provider endpoint\n- Tool is only registered when remote search is enabled and the cloud provider is active\n- Consent prompts, docs, and MCP tooling no longer reference DuckDuckGo or expose web_search_detailed
Test Notes:\n- cargo check
Acceptance Criteria:\n- header shows hourly/weekly usage with colored thresholds\n- :limits command prints persisted usage data and quotas\n- token usage survives restarts and emits 80%/95% toasts
