`Response.json(data, init)` was refused (SC2020). It now builds a native
Response the way undici does: ResponseInit converts, the data serializes
through the checked-dynamic JSON serializer (toJSON hooks included;
TypeError "Value is not JSON serializable" when JSON.stringify answers
undefined), then the response initializes like the constructor with
"application/json" as the default content type, so status, statusText,
header, and null-body-status errors keep their order.
The fetch compatibility profile moves Response.json from unsupported to a
static operation with the static-response-json differential fixture.

* Expand static compilation for common Effect 4 patterns
* Run every Effect 4 fixture slice in CI
* Preserve existing corpus behavior across Effect 4 lowering
* Preserve Effect platform callbacks and native stream state
* Record new corpus baselines and retain child stdin refusals
* Retire the obsolete stateful regex diagnostic
* Preserve promise reference count layout for cycle collection
- Support integer widths and clamped arrays with shared storage and exact runtime brands.
- Preserve typed-array values through untyped fields, iteration, and byte I/O.
- Compile native ArrayBuffer response bodies and checked Number predicates.
- Run production scope and closure capture logic with native TypeScript 7 symbols.
- Give lowering caches explicit pass ownership and stable symbol identities.
- Support reference collection arrays and optional Set seeds on both native backends.
* Lower AbortController for fetch cancellation
- Add static and dynamic lowering for construction, signal access, and abort calls
- Back controllers with native signal state shared by fetch
- Cover cancellation semantics across C, LLVM, diagnostics, and surface tests
