v0.2.0 — from demo to product

Reweave now does real work end to end:

• ✨ Zero-selector onboarding — paste a URL + 2 golden examples; the Surgeon synthesizes and validates the extraction spec (POST /api/sources, reweave add, MCP add_source, dashboard ＋ Add source). Verified against the live web: 3 examples → 20 rows at 100% confidence on books.toscrape.com.
• 🧲 Attribute anchoring — golden values found in text or attributes (title=/alt=), per-shape candidate groups, most-specific container selection: a few examples generalize to the whole page.
• 📦 Data out — every run stored, data drawer in the dashboard, CSV/JSON export, MCP get_rows.
• 🛰️ Autopilot — continuous monitoring; repairs still deploy only through the human gate.

20 tests, lint clean. Full notes: CHANGELOG.md
