• Fixed PKPToolPolicyRegistry.sol path reference

Testing

• Verified all updated package links match existing directory structure
• Confirmed CONTRIBUTING.md follows standard open source practices
• Checked that external link to Lit faucet is working

The CI failure appears to be a configuration issue with nx affected commands. The command is trying to compare against 'main' branch, but our PR is targeting 'v3'.

I suggest updating the CI workflow to use the correct base branch. This can be done by setting NX_BASE=origin/v3 in the workflow environment.

For now, since this PR only contains documentation changes (fixing broken links in README.md and adding CONTRIBUTING.md), these changes don't affect any package code and shouldn't require nx affected checks. Could we get this PR reviewed and merged, and then address the CI configuration in a separate PR?
