AI skill may silently omit user-provided local phone numbers

Problem

The AI agent skill currently says:

If the user provides a local number without country code, ask which country, or omit the phone field.

RenderCV requires international phone numbers, while cv.phone is optional. This allows an agent to silently discard a phone number the user explicitly provided instead of resolving the missing country code.

Expected behavior

For a local number, the agent should ask which country it belongs to. It should neither guess the country code nor omit the number without the user's explicit permission.

Example

A request such as Create a CV for Sam Lee. Their phone number is 020 7946 0958. should trigger a country clarification before the final CV is generated.

Proposed fix

Make the instruction deterministic and add an agent eval covering the clarification, no-guessing, and no-silent-omission requirements.
