Matt Aitken c084fa6e29 fix(sdk,react-hooks): forward debounce when batch triggering with an array (#4520)
Passing `debounce` in the per-item options of a batch trigger did
nothing when the items were an array. The option was accepted by the
types and by the API, then dropped before the request went out, so every
item created its own run instead of collapsing onto the debounce key.

Four public entry points were affected: `task.batchTrigger`,
`task.batchTriggerAndWait`, `tasks.batchTrigger`, and
`tasks.batchTriggerAndWait`. The streaming (async iterable) forms of the
same calls were already correct, as were `batch.trigger`,
`batch.triggerAndWait`, `batch.triggerByTask`, and
`batch.triggerByTaskAndWait`.

`useTaskTrigger` in `@trigger.dev/react-hooks` had the same silent drop
on the single-trigger path, so that is fixed here too. It also drops
`machine`, `priority`, `region`, `idempotencyKeyTTL`, and
`idempotencyKeyOptions`; those are left alone, since forwarding them is
a behaviour change beyond this bug.

Each batch item builder constructs its options field by field, which is
why one of them could fall behind without anything catching it.
TypeScript did not help: the literal is returned from a `.map` callback
inside `Promise.all`, so excess-property checking never fired against
the `BatchItemNDJSON[]` annotation, and the server's schema silently
strips unknown keys. A misspelled option name therefore reproduced this
bug with no compile error and no server error. Every builder now ends in
`satisfies BatchItemNDJSON`, which does catch it:

```
error TS2561: Object literal may only specify known properties, but 'debounceTYPO'
does not exist in type '{ ... debounce?: {...} | undefined; }'.
Did you mean to write 'debounce'?
```

The new test drives all six public batch surfaces in both array and
async-iterable form and asserts on the NDJSON that actually reaches the
wire. Each item carries a distinct debounce key so the test catches a
wrong item-to-option pairing, not just a wholesale drop.
