When the user asks about a vehicle's price, worth, or market value and has a VIN:

Optionally refine the estimate with these parameters if the user mentions them:
- state — US state code (e.g., CA, TX) for regional pricing
- mileage — current mileage to adjust the value
- condition — vehicle condition: excellent, clean, average, or rough
Make an HTTP GET request to the CarsXE Market Value API:
```
GET https://api.carsxe.com/v2/marketvalue?key={CARSXE_API_KEY}&vin={VIN}&source=codex_plugin
```
Append &state=<STATE>, &mileage=<MILEAGE>, and/or &condition=<CONDITION> if provided.
Present the estimated market value clearly, including:
- Current value estimate
- Low / average / high range if available
- Historical trend if available
Provide helpful context (e.g., whether the value is strong for its age/mileage).
If the API key is missing, tell the user to set the CARSXE_API_KEY environment variable (see AGENTS.md).
