Commit Message

Publish through the typed entry point only, with a codec-optional surface and a batch-aware harness (#281)

* test: pin the test client on the serialized lane

The lanes tests cover what a handler publishes, but nothing covered what
the test client injects. A `Serialized` value handed to `message(..)` has
to reach the subscription the way the service's own publish path sends
it: the destination read off the declaration, and the bytes untouched by
any codec.

* fix: keep the declared return type on a settling handler body

A settling handler expanded into an `IntoOutcome` conversion over an
unascribed async block, so the body was type-checked with nothing naming
its output. `IntoOutcome` is implemented for `Result<_, E>` over any `E`,
which left a body returning `Result<(), HandlerOutcome>` with a bare
`Ok(())` and no `?` anywhere unable to infer the error type: the
signature named it, the expansion dropped it, and the handler failed to
compile with E0282.

Ascribe the block with the type the signature declares, the way the page
form already did, so a body infers exactly as it does in a plain
function.

* fix: record the page a batch handler was called with

The dispatcher wrote a harness record only on the single-message path, so
a batch subscription was invisible to every subscriber assertion:
`assert_called_once` saw zero calls, and `received_raw` returned nothing
however many pages had arrived.

Record the page where every batch form already funnels through, the
settle choke point that knows both the deliveries and the settlements
they got, reaching the harness through the task-local scope the slot
recorder already rides. A record now carries the deliveries of one
handler CALL: exactly one for a single-message handler, one per element
for a page.

The assertions keep their meaning on the single path and gain a defined
one for pages: `assert_called_once` is one page whatever its size,
`received_raw` lists its elements, `settled` covers every element... (continued)
