Igor Sirotin d5d5a215ed refactor: build against the single liblogosdelivery library
logos-delivery#4012 unifies the node lifecycle on logosdelivery_* and ships the
full API — Messaging, Reliable Channels, and the low-level Kernel (waku_*) tier
— in one liblogosdelivery library, retiring the separate libwaku. Migrate the
bindings onto it.

- internal/ffi: collapse the two bridges into one internal/ffi/liblogosdelivery
  over the single library. The kernel wrappers keep calling waku_* (kernel
  header), the lifecycle now uses logosdelivery_create_node/start_node/
  stop_node/destroy (waku_new/start/stop/destroy are gone), events use
  logosdelivery_set_event_callback. Include liblogosdelivery_kernel.h (which
  re-exports the stable header) and link -llogosdelivery. Remove
  internal/ffi/libwaku.
- pkg/kernel: repoint at internal/ffi/liblogosdelivery; the Makefile links
  -llogosdelivery.
- CI: build only `make liblogosdelivery`, headers from library/, single
  -llogosdelivery. Pinned to logos-delivery#4012 until it merges (see the
  TODO/LOGOS_DELIVERY_REF in pr.yml).

The high-level MessagingClient (pkg/messaging) lands in a follow-up PR on top.
