refactor: remove wormhole-attester directory

The wormhole-attester functionality has been consolidated into pythnet-sdk
to simplify the codebase and reduce duplication. This change:
- Moves protocol constants to pythnet-sdk
- Updates Near and Cosmwasm contracts to use pythnet-sdk directly
- Removes the deprecated wormhole-attester package
