libp2p was pulled in solely for its `minprotobuf` field codec, dragging
in its full transitive tree (secp256k1, nimcrypto, websock, etc.). Swap
it for nim-protobuf-serialization, whose low-level `codec` module gives
the same protobuf wire primitives without the networking stack.
The wire/snapshot codecs build messages by hand at the field level and
rely on a backward-compatible decode path the type-driven
`Protobuf.encode/decode` API cannot express. To keep that code intact,
`protobufutil.nim` is a thin `ProtoBuffer` shim over the new `codec`
module, preserving the exact field-level behaviour the codecs depend on
(plain varints, length-delimited bytes/strings with no UTF-8 validation,
unknown-wire-type fields skipped as protoc does).
Dependency closure (nimble.lock, nix/deps.nix) regenerated accordingly:
libp2p and its 8 exclusive transitive deps dropped, protobuf_serialization
and its npeg dependency added.

Changes include:
- Removing all submodules from vendor folder.
- Updating sds.nimble with required depndencies.
