test(e2e): Port cloudflare-workers to span streaming and keep a static copy (#23855)

Ports `cloudflare-workers` to span streaming and keeps the static trace
lifecycle covered, via two renames:

- `cloudflare-workers` → `cloudflare-workers-static`: verbatim, stays on
`traceLifecycle: 'static'` with the transaction-based specs. Only the
app name changes (`package.json` `name`, `proxyServerName` in
`start-event-proxy.mjs`, the proxy name in every `waitFor*` call in
`tests/`, and the wrangler worker `name`).
- `cloudflare-workers-streaming` → `cloudflare-workers`: same name
changes, plus the explicit `traceLifecycle: 'stream'` pin is dropped so
the app exercises the default lifecycle. Its basic-request test now also
pins the segment name: the root path `/` is a `route` source, so the
span keeps the full `GET /` name under streaming.

Renaming instead of copying keeps both apps' history followable and
keeps the diff down to the name changes. Because the path
`cloudflare-workers` exists before and after, git pairs the rename as
`-streaming → -static` and shows `cloudflare-workers` as modified; the
file contents follow the two moves above.

Side effect of the rename: `cloudflare-workers` inherits the
`-streaming` app's active memory test (`memory.test.ts`, already running
in CI for that app); the two skipped memory tests stay with
`cloudflare-workers-static`.
