Why it's needed:

Explain how this PR fits in the greater context of the NuCypher Network. E.g.,
if this PR address a nucypher/productdev issue, let reviewers know!

Notes for reviewers:

• Ignore failing CI integration tests for now (other tests pass) - this is because lynx nodes aren't running the latest changes from Common signing objects from nucypher-core nucypher#3646. If they did, then current signing flows would fail. My plan is to update lynx nodes, porter, contracts, latest nucypher/taco npm package all within a single maintenance day - that day is currently undecided.
• Since this is related to SigningCoordinator changes (Signing Request key nucypher-contracts#438) - I also need to regenerate agents code based on updated contract before merging.

Pull Request Overview

This PR migrates from using a published NPM package version of @nucypher/nucypher-core (v0.14.5) to a local link dependency, and refactors UserOperation signing to use native WASM types instead of JSON serialization. The changes improve type safety and leverage the WASM core library's built-in types and serialization.

Key Changes:

• Replace @nucypher/nucypher-core: ^0.14.5 with link:../nucypher-core/nucypher-core-wasm-bundler across all packages
• Refactor UserOperation/PackedUserOperation handling to use native UserOperationSignatureRequest and PackedUserOperationSignatureRequest from nucypher-core
• Add converter functions (toCoreUserOperation, toCorePackedUserOperation) to bridge between TypeScript types and WASM types
• Update test mocks to use SignatureResponse class instead of JSON-based signatures
• Add validator index parameter to Validator constructor
