Public API & MCP upgrade

We've massively expanded what our public API and MCP can do. External tools, AI agents, and our own reporting agents can now pull almost everything the dashboard shows, automatically, with the same numbers as the UI.

What's new:

• Google Analytics (GA4): AI-driven traffic, referrals, top pages, and traffic sources, available directly via API.
• Sources: which sites and pages cite the brand, with content types, trends, and full drill-down.
• Sentiment: brand sentiment, history, and head-to-head competitor comparison.
• Location: visibility broken down by country and region, plus location filters on sentiment and sources.
• Query fanout: the follow-up questions AI engines ask while answering a prompt.
• Opportunities: now surfaced via the API.
• On-demand reports: generate shareable visibility and combined reports via API (previously sentiment-only).
• Trigger audits on demand: kick off audits from any external tool or agent.
• White-label and unbranded outputs: plus pagination for large datasets, expanded docs, and live tests.
• Speed boost: visibility and sentiment reads now run on ClickHouse, purpose-built for this kind of querying, so responses are dramatically faster. Every fast path ships with parity tests that prove it returns the exact same numbers as before.

Net effect: our AI connector grew from 8 to 30 tools, roughly 4x. Agents can now answer far richer questions about a brand's AI visibility without anyone exporting data by hand, and everything is much quicker.
