Pull request overview

This PR adds an opt-in compatibility toggle to pnpm-plugin-skills to strip pnpmfileChecksum from the generated pnpm lockfile after resolution, addressing temporary interoperability needs (per the linked Renovate discussion).

Changes:

• Introduces a temporary pnpmPlugin.removePnpmFileCheckSum config flag consumed by pnpm-plugin-skills.
• Adds an afterAllResolved hook implementation that deletes pnpmfileChecksum when the flag is enabled.
• Adds tests for both the opt-in removal behavior and the default no-op behavior.
