docs(readme): make v3 the current focus with a clearly labeled section

 A Go FinOps toolkit that ships in two modes from the same `oracle` binary, with a polyglot agent extension in progress:
 
 - **v1 — Audit existing cloud spend.** Ingest live EC2/RDS/EBS/Lambda inventory from AWS, GCP, or Azure into Postgres, run deterministic rules over it, and produce an executive PDF + dashboard with an LLM-narrated summary. See **[docs/v1-guide.md](docs/v1-guide.md)**.
-- **v2 — Predict cost impact of a Terraform PR before merge.** Read `terraform show -json plan.tfplan`, look every changing resource up against the AWS Pricing API, and post (or upsert) a Markdown comment on the PR with the net monthly delta, top movers, and a 1–3 sentence LLM narrative. Ships as a GitHub Action and as the `oracle pr-check` subcommand. **Current focus.** See **[docs/v2-guide.md](docs/v2-guide.md)**.
-- **v3 — Insights Agent.** Polyglot Go + Python extension adding agentic FinOps analysis on top of v1/v2 cost data — a hand-rolled LangGraph supervisor over specialist agents, RAG over a FinOps corpus (pgvector), production guardrails, real billing via AWS Cost Explorer, and a CLI + HTTP surface. See **[docs/v3-guide.md](docs/v3-guide.md)**, **[AI Insights Agent](#ai-insights-agent)** below, and **[insights-agent/README.md](insights-agent/README.md)**.

 - [X]  **Milestone 8.0** — Authenticated `/api/v1/cost-summary` and `/api/v1/cost-by-service` Go endpoints (X-API-Key, snapshot-derived totals with explicit `data_source` disclaimer, machine-readable error codes)
 - [X]  **Milestone 8.1** — Python `insights-agent` sibling: LangGraph `create_react_agent` graph with two CloudOracle tools, Gemini provider, pydantic-settings config, structlog matching the Go slog format, CLI with `--verbose` / `--json` flags, 92% test coverage with mocked LLM + mocked HTTP.
