d342d0b91f Trace cacheHandler and cacheHandlers when using adapters (#94197)
### What?

Add focused production adapter coverage for configured `cacheHandler`
and `cacheHandlers` module graphs in Node `output.assets`, including
transitive helper dependencies and Turbopack `assetsHashes` assertions.

### Why?

Adapter deployments dynamically load configured cache handlers at
runtime. This coverage demonstrates that Node adapter outputs currently
omit those handler files and their transitive dependencies.

### How?

Add an App Router Cache Components fixture using `adapterPath`, both
cache-handler APIs, and a `use cache: remote` route. Its adapter writes
`onBuildComplete` context to disk and the test inspects Node outputs for
each handler and uniquely named helper.

### Verification

- `NEXT_TEST_PREFER_OFFLINE=1 pnpm --filter=next build`
- Expected failure: `NEXT_TEST_PREFER_OFFLINE=1 pnpm test-start-turbo
test/production/app-dir/adapter-cache-handlers/adapter-cache-handlers.test.ts`
(no Node output contains all four handler assets)
- Expected failure: `NEXT_TEST_PREFER_OFFLINE=1 pnpm test-start-webpack
test/production/app-dir/adapter-cache-handlers/adapter-cache-handlers.test.ts`
(same adapter handoff gap)
- `git diff canary --check`
- Not run continuously: `pnpm --filter=next dev` (`EMFILE: too many open
files` occurred after startup in the local watcher)
