Completes the second cut of FINAL_RIP.md. The first cut (a0aab0a) dropped
the codec.Registry field from each fx's VM interface and the public API
codec.Manager params. This cut removes the remaining test-side residue:
- Strip `linearcodec.NewDefault()` Codec field literals from every TestVM
(the field no longer exists on TestVM).
- Drop the obsolete `TestCredentialSerialize`, `TestTransferInputSerialize`,
and `TestOutputSerialize` tests in secp256k1fx — they asserted the
legacy linearcodec wire-byte format. ZAP-native round-trips are covered
in wire/wire_test.go and the per-fx wire_test.go files.
- `go mod edit -droprequire github.com/luxfi/codec` + tidy — codec is now
indirect-only (transitively required via github.com/luxfi/vm for the
verify.State interface).
Build + test clean across all 11 packages. ZAP-native at the activation
boundary 2025-12-25T16:20:00-08:00.
