* change all usage of std.options.Option[T] to results.Opt[T] * fix broken apps and examples (to validate refactor) * removed all std/options code added for libp2p v2 migration * add broker Opt codec to persistency/backend_comm.nim * add a readValue overload for Opt[T] in tools/confutils/cli_args.nim * keep Option where required (Presto, confutils' config_file.nim) * Change generateRlnProof error handling * Fix imports

## Waku layer API — message publish primitives used by the messaging send

## pipeline.

## Unlike `relay.nim`/`lightpush.nim`, these preserve the rich
|
|
## `WakuLightPushResult` (status code + description) that the send processors
|
|
## branch on for their retry decisions, and expose relay/lightpush availability
|
|
## so the messaging layer never inspects `waku.node` directly.
