Adds github.com/luxfi/utxo/wire package + per-fx wire.go adapters so
that luxfi/node's vms/{platformvm,xvm}/txs/codec.go can be deleted.
wire/ package mirrors luxfi/node/vms/wire — every fxs primitive carries
a (TypeKind, ShapeKind) discriminator pair on its wire envelope, then
a ZAP message describing its fields. Decomposes the legacy
codec.Manager slot map (which braided "fx family" and "primitive shape"
into a single dense uint32 slot id) into two orthogonal 1-byte tags.
PQ-specific schemas (pq_output_owners, pq_transfer_output,
pq_mint_output) handle the mldsafx/slhdsafx case where addresses are
full PQ pubkeys (1312-2592 bytes) rather than 20-byte hashed ShortIDs.
The wire layer is stride-agnostic — the per-fx wire.go resolves
SecurityLevel → pubkey stride before parsing.
Per-fx wire.go adapters provide (value T).Bytes() []byte (Go type →
wire envelope) and Wrap*(b []byte) (*T, error) (wire envelope → Go
type). The Initialize(vm)/codec.Manager.RegisterType chain stays in
place pending downstream coordination; this commit gets the wire/
package + adapters in so consumer agents (platformvm/warp,
platformvm/state, xvm) can pin a SHA and start their migrations.
UTXO.WireBytes() builds the outer envelope by calling the polymorphic
Out's Bytes() (any fxs primitive implementing wireSerializable).
WrapUTXOBytes(b) parses the outer envelope; the inner output is
dispatched by the caller via OutputDiscriminator() → fx-package
WrapTransferOutput / WrapMintOutput / WrapAttestationOutput.
Tests: 35 round-trip tests across 9 packages. go vet clean. go test
-race clean. gofmt clean.
Activation: 2025-12-25T16:20:00-08:00 (unix 1766708400). No
backwards compat — pre-activation legacy codec blobs are a
protocol-violation reject after activation.
