Curate the lawn mower model registry (data + schema)

[Forenly]

Build the registry the agent recommends FROM.

Deliverables

• Define mower model schema (brand, model, max area m², slope tolerance %, GPS/wire mapping, app ecosystem, price tier, etc.)
• Seed registry with 10-20 popular models (Husqvarna Automower, Worx Landroid, Ecovacs Goat, Stihl iMow, Mammotion, etc.)
• Store in MongoDB collection (so MCP can query it)
• Sample queries the agent will run ("max 800m² + 30% slope + budget tier 2")
• Document data shape in docs/MOWER_REGISTRY.md
