Fixes six bugs in Pages SSR: deferred props, action responses, and dev rescans.

Bug	Before	Now
A page scan error during a dev rescan (e.g. layout: docs before _layouts/docs.* exists)	unhandled rejection, void dev exits	the error is logged and the last good scan is kept; the next change rescans
A deferred value whose object has a key named like another deferred prop	the value lands in that other prop, and its own prop never resolves	a group resolves only its own keys
A deferred resolver that throws, in prefetch or prerender	silent null, baked into _void/pages/*.json	sent as deferredErrors, and the client rejects that prop as it does when streaming
A deferred resolver that returns undefined, on client navigation	stays loading forever	resolves to null, as on a full page load
A loader that returns a redirect or 404 after an action	page renders with {} props	the loader's Response is returned, as on a GET
A 400 from an action that is not from withValidator	a text body becomes a 500; a JSON body is swallowed	passed through unchanged; only an issues body becomes field errors

How

protocol.ts         runLoader(): one rule for GET and post-action loader runs
                    prefetch: deferredErrors per failed group; undefined → null
                    NDJSON: data ?? null
                    400: clone().json() → issues[] ? field errors : pass through
navigation-engine   resolveGroup: one key → raw value; several keys → value[key]
                    setup(resolved): a key whose group is in deferredErrors is rejected
                    retainOnly keeps full groups, so a preserved part of a group still splits correctly
islands-plugin +    rescan errors are handled; the adapter pages plugin logs them once
4 adapter plugins

The deferred rule is the one the server's prefetch path and the docs ("Grouped Deferred Props") already use.

Tests

• New tests: 17, in pages-client, pages-protocol, the new pages-islands-rescan, and the react/vue/svelte/solid plugin-pages tests. All 17 fail on main.
• Unit tests: the pages, prerender and island files in void pass (326 tests), as do all the adapters' unit tests.
• Browser tests: React 44/44 and Vue 30/30.
• Checks: typecheck for void and the 4 adapters, lint and format are clean.
