pnpm-matureUpdate dependencies only after they have aged.

Compute maturity caps from npm publish dates, then let pnpm resolve everything normally.

Preserve pnpm behavior

pnpm-mature does not replace pnpm's resolver, lockfile generation, or peer dependency handling.

Select the newest semver-compatible version older than your configured age threshold.

Write the selected direct dependency versions into package.json, then let pnpm resolve and lock them.

Inspect selected versions, skipped recent releases, and generated constraints before changing anything.
