zpm-config: accept numeric scalar values for interpolated settings

[hamidrezahanafi]

Why this change needed?

• npmMinimalAgeGate: 0 inside .yarnrc.yml can't be parsed correctly

Summary

• allow Interpolated<T> deserialization to accept numeric YAML scalars in addition to strings
• convert numeric scalars to strings before passing through FromFileString
• preserve existing string interpolation behavior for env-based string values

Test plan

• cargo build --release -p zpm
• Updated Existing acceptance coverage is in tests/acceptance-tests/pkg-tests-specs/sources/features/npmMinimalAgeGate.test.ts to add coverage

Confidence Score: 4/5

• Safe to merge with minimal risk - straightforward deserialization enhancement
• The implementation correctly handles numeric YAML scalars by converting them to strings before parsing. The approach is sound and maintains backward compatibility. Minor edge case with float scientific notation could theoretically occur but is unlikely in practice for duration values.
• No files require special attention

Important Files Changed

Filename	Overview
packages/zpm-config/src/lib.rs	Added Integer and Float variants to StringOrAnything enum to support numeric YAML scalars, converting them to strings before parsing
tests/acceptance-tests/pkg-tests-specs/sources/features/npmMinimalAgeGate.test.ts	Added test case to verify numeric npmMinimalAgeGate (0) can be parsed from .yarnrc.yml
