P1 Operation type remains v0.6

When a developer copies the displayed example.ts and types.ts snippets, the v0.7 operation is checked against a type that still requires initCode and paymasterAndData and excludes the new factory and paymaster fields, causing TypeScript compilation to fail.

P1 Empty paymaster becomes present

When the default example is used without a paymaster, toPackedUserOperation treats the truthy "0x" paymaster as present and produces non-empty paymaster data containing the zero address, causing EntryPoint validation to reject the operation.
