Subject: [PATCH 1/2] zpm-config: accept numeric scalar values for interpolated
 settings

Allow interpolated configuration fields to deserialize numeric YAML scalars by converting them to strings before parsing. This preserves existing string interpolation behavior while fixing configs like npmMinimalAgeGate: 0.

Subject: [PATCH 2/2] tests: cover numeric npmMinimalAgeGate from .yarnrc.yml

Add an acceptance test that writes npmMinimalAgeGate as a numeric YAML scalar in .yarnrc.yml and verifies install succeeds. This exercises file-based config parsing rather than env-based overrides.
