warp-wasm still speaks CBOR everywhere except the EINT path

Status: bad code.

Where

crates/warp-wasm/src/lib.rs and crates/warp-wasm/src/warp_kernel.rs.

Smell

Per the 2026-05-28 audit (during 0024 universal LE binary codec
Phase 3):

• Public ABI exports named *_cbor: dispatch_intent_cbor,
  observe_cbor, get_registry_info_cbor,
  dispatch_control_intent_trusted_cbor, plus optic/settlement variants.
• observe_cbor decodes ObservationRequest as CBOR
• dispatch_optic_intent decodes DispatchOpticIntentRequest as CBOR
• observe_settlement* / read_settlement* decode requests as CBOR
• ALL response envelopes (OkEnvelope<T>, ErrEnvelope) are
  CBOR-encoded
• warp_kernel.rs reports codec_id = "cbor-canonical-v1" while the
  EINT payload path is fully LE binary — inconsistent self-description

Why it matters

The mutation path goes EINT-in / CBOR-out today. That works because
jedit can CBOR-decode the response envelope, but it means:

• The "engine native protocol" claim is half-true; queries still need
  CBOR-encoded ObservationRequest from jedit
• Function names mislead consumers about the actual wire format
• codec_id advertises the wrong protocol

Suggested cycle

1. Add Encode/Decode impls for ObservationRequest,
   DispatchOpticIntentRequest, SettlementRequest, OkEnvelope<T>,
   ErrEnvelope
2. Rename *_cbor exports to *_wire (or similar). Hold the rename
   under a feature flag so jedit can adopt the new names in lockstep.
3. Update codec_id to le-binary-v1
4. Update jedit echo-wasm-kernel.ts consumer to call the new names

This is multi-turn. Don't attempt until the mutation cutover
(jedit/spec/rope-codec.spec.mjs, jedit/spec/eint.spec.mjs) has been
proven end-to-end.

Surface when

After the jedit optic-client EINT cutover lands and the user wants to
move queries onto LE binary.
