* feat(messaging): object-oriented Go mirror of the Nim MessagingClient
Adds pkg/messaging: a high-level, idiomatic Go binding for the Messaging
API, mirroring logos-delivery's Nim MessagingClient. A MessagingClient owns
a node and carries the messaging surface as methods on it — New / Start /
Stop / Close, Subscribe / Unsubscribe, Send(ctx, Envelope) (RequestID,
error) — over internal/ffi rather than exposing the raw FFI.
Events arrive on a single Events() <-chan Event with a sealed Event
interface: MessageReceivedEvent, MessageSentEvent, MessagePropagatedEvent,
MessageErrorEvent and ConnectionStatusEvent. Delivery never blocks the
library's event thread; an event is dropped when a consumer falls behind.
Config marshals to the layered configuration JSON (mode / preset /
messagingOverrides / channelsOverrides), with every field omitempty so it
can never be mistaken for the legacy flat blob.
Migrating internal/ffi to the current C ABI comes with it, because the
generated surface has moved on since the bridge was written and no longer
compiles: nim-ffi now generates the header from the {.ffi.} annotations,
argument-taking calls pass a per-call <Name>Req struct and a typed
<Name>ReplyFn, no-argument calls take a raw scalar callback, destroy is
synchronous, and the single set_event_callback has been replaced by a
per-event listener registry. The bridge now also copies every callback
string while it is still borrowed, and ignores the non-terminal
STALE_WARN progress code instead of settling the call on it.
pkg/kernel follows the same listener change, registering the three kernel
events it already consumed.
Verified against a liblogosdelivery built from logos-delivery master:
build / vet / golangci-lint / go mod tidy clean, unit tests green, and the
tagged integration test does a full create-start-subscribe-send round trip
on logos.dev, observing the message back and its propagation confirmation.
Closes#119.

* review: address feedback on the MessagingClient API
- Send takes contentTopic / payload / ephemeral directly instead of an
Envelope struct, which drops the Envelope type; ContentTopic and RequestID
move to types.go.
- messagingEvents becomes a function returning the slice, so the set cannot
be mutated by accident.
- Document what seals the Event interface and what that buys callers.
- Document why the received payload is decoded from a JSON integer array:
base64 is only used on the send path and by the channel events, not by the
messaging events.
* ci: stop golangci-lint's config verify from failing on a network timeout
golangci-lint-action runs `golangci-lint config verify` before linting, which
fetches the v2.4 JSON schema from golangci-lint.run on every run. That request
timed out on the runner and failed the gate with no lint finding behind it. An
invalid config still fails the lint run itself, so the pre-check only costs a
network dependency.

* 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).
