[F33] mxaccess-asb: complete InvalidConnectionId tolerance propagation
Closes F33. Final commit in the three-step F33 closure (218f4c47a5f251 → this) — propagates the F31 InvalidConnectionId tolerance
pattern to every remaining response decoder + adds publish-loop
detection so the F26 stream terminates cleanly on server-side
rejections instead of spinning silently.

Decoders updated to tolerate empty / missing payloads + surface
result_code/success:
  - decode_publish_response (the F26 stream's hot path)
  - decode_unregister_items_response
  - decode_delete_monitored_items_response
  - decode_write_response
  - decode_publish_write_complete_response

Shared `extract_result_status(body_tokens)` helper in operations.rs
consolidates the per-decoder find_text_in_named_element calls for
resultCodeField + successField — a single source of truth for the
F31-pattern wrapper extraction.

Public response structs gain `result_code: Option<u32>` and
`success: Option<bool>`:
  - PublishResponse
  - UnregisterItemsResponse
  - DeleteMonitoredItemsResponse
  - WriteResponse
  - PublishWriteCompleteResponse

asb_session.rs::publish_loop: when PublishResponse.result_code is
Some(non_zero), the loop now sends Err(ConnectionError::TransportFailure
{ detail: "publish returned result_code 0xXX (server-side rejection)" })
as the stream's terminal item, then returns. Without this, an
InvalidConnectionId-poisoned subscription would generate empty
PublishResponse forever.

5 new tests synthesise the InvalidConnectionId wire shape
(`<Result><resultCodeField>1</><successField>false</></><ASBIData/><ASBIData/>`)
for each decoder via the shared synthesise_invalid_connection_id_body
helper — pin the tolerance for Publish, Unregister, Delete*, Write,
and PublishWriteComplete.

Updated obsolete write_response_missing_status_fails test to
write_response_missing_status_returns_empty_with_no_result_code
since the decoder no longer errors.

Live read regression test: TestChildObject.TestInt = 99 returned
end-to-end after all changes (cargo run -p mxaccess --example
asb-subscribe).

Workspace: mxaccess-asb 82 → 87 tests (+5). All other crates
unchanged. Default-feature clippy clean.

design/followups.md: F33 moved to Resolved with the full
three-commit audit trail. M5 status block stable: F32 + F33 closed,
only F28 (canonical XML for the remaining 8 ops) remains as P2
latent — works in practice under empty hashAlgorithm.

//! Per-operation request / response NBFX-token builders for
//! `IASBIDataV2`.
//!
//! Each `IAsbCustomSerializableType`-decorated field in a request
//! contract is serialised by WCF's `AsbDataCustomSerializer`
//! (`AsbContracts.cs:1561-1599`) as:
//!
//! ```xml
//! <FieldName xmlns="urn:msg.data.asb.iom:2">
//! <ASBIData>{base64-binary}</ASBIData>
//! </FieldName>
//! ```
//!
//! The `<ASBIData>` element body is the binary `WriteToStream` /
//! `WriteArrayToStream` output, written via `WriteBase64`. In the NBFX
//! wire form we get from the WCF binary encoder, `WriteBase64` emits a
//! `Bytes8/16/32Text` record (raw binary, NOT base64 text — base64 is
//! the XML-text representation of the same bytes).
//!
//! ## Scope this iteration (F25 step 2)
//!
//! Implements:
//! * [`build_register_items_request_body`] — `RegisterItems` request
//! contract per `AsbContracts.cs:119-143`.
//! * [`build_unregister_items_request_body`] — `UnregisterItems`
//! request per `cs:145-159`.
//!
//! Stubbed for next F25 iteration:
//! * `Read`, `Write`, `PublishWriteComplete`, `CreateSubscription`,
//! `AddMonitoredItems`, `DeleteMonitoredItems`, `Publish`. Each
//! follows the same NBFX-token pattern; the per-operation cost is
//! small once the `RegisterItems` reference is set.
//! * Response decoders. Same pattern in reverse: the reply envelope's
//! body tokens carry a per-operation outer element wrapping
//! `<ASBIData>` Bytes records, each decoded via the corresponding
//! `InitializeArrayFromStream` shape.
