  1. Introduce Dummy Hop support in Blinded Path Constructor 

    Adds a new constructor for blinded paths that allows specifying
the number of dummy hops.
This enables users to insert arbitrary hops before the real destination,
enhancing privacy by making it harder to infer the sender–receiver
distance or identify the final destination.

Lays the groundwork for future use of dummy hops in blinded path construction.

  2. Refactor: Introduce ForwardInfo 

    NextPacketDetails currently bundles four fields used to define the
forwarding details for the packet. With the introduction of dummy
hops, not all of these fields apply in those paths.

To avoid overloading NextPacketDetails with conditional semantics, this
refactor extracts the forwarding-specific pieces into a dedicated
ForwardInfo struct. This keeps the data model clean, reusable, and
makes the logic around dummy hops easier to follow.

  4. Update PaymentPath, and ClaimAlongRoute arguments 

    Upcoming commits will need the ability to specify whether a blinded path
contains dummy hops. This change adds that support to the testing
framework ahead of time, so later tests can express dummy-hop scenarios
explicitly.
