* refactor: extract libwaku cgo bridge into internal/ffi
Move the C preamble, cgo shims, and callback plumbing from pkg/kernel/nwaku.go
into internal/ffi/libwaku.go, where #111 scaffolded them to live. The bridge
exposes Go-typed Waku* primitives (handle in, strings out) and owns the
handle->event-handler registry, so pkg/kernel is now pure Go: WakuNode keeps
its full API, logging, and error texts, and just calls ffi.
Behavior is unchanged. Dropped four C shims that had no Go callers
(cGoWakuContentTopic, cGoWakuPubsubTopic, cGoWakuDefaultPubsubTopic,
cGoWakuLightpushPublish). CGO flags still come from the environment
(Makefile/CI untouched).
Part of #106.

* refactor: move libwaku bridge into internal/ffi/libwaku subpackage
One subpackage per C library so a binary links exactly the libraries it
imports: libwaku and liblogosdelivery carry overlapping symbols and must never
link together (until logos-delivery#3851). With the package named libwaku the
Waku* prefixes became stutter, so the exported primitives drop them
(libwaku.New/Start/RelayPublish/...). internal/ffi keeps an umbrella doc.go
stating the rule.

* refactor: adopt golang-standards/project-layout
Move the legacy kernel wrapper `waku/*` to `pkg/kernel/*` and rename its
package `waku` -> `kernel`; nothing outside the package imported it, so this is
a mechanical import-path/prefix change. Update the relocated Makefile's
relative dep path, the legacy CI workflows (CI/endurance/repeated) build paths,
README, and .gitignore accordingly (preserving the libwaku-cache CI from #109).
Add scaffolding for the upcoming Messaging API work: `internal/ffi` (cgo
bridge), `pkg/messaging` (high-level Node API), and `examples/`. Document
`pkg/kernel` as legacy until logos-delivery#3851 consolidates the C libraries.
Also stop tracking the accidentally-committed `waku-bindings` build artifact
and gitignore the kernel build output.
No behavior change.

* chore: cleanup
* fix: repair references to removed utils package
nwaku_test_utils.go now uses pkg/kernel/utils.GetRSSKB; the memory_record
tool is self-contained (local helpers, missing mutex restored).
