What

Ports react-create-browser-router, react-create-hash-router and react-create-memory-router to span streaming.

Why

Span streaming is the default now, so the E2E suite has to exercise it. Two attribute groups moved and the assertions follow them: the navigator data is now device.memory.estimated_capacity, device.processor_count and network.connection.effective_type, and the pageload timings are browser.performance.*. LCP is streamed as its own ui.webvital.lcp span once the page hides, so it is no longer asserted on the pageload span.

Part of #23798

test(e2e): Add a static trace lifecycle React Router E2E app
436f969
Copies `react-router-7-framework` into `react-router-7-framework-static`, which
keeps `traceLifecycle: 'static'` and its transaction-based specs. The rest of the
React Router group moves to span streaming in the PRs above, so this copy is what
keeps the static lifecycle covered.
The copy drops the `latest` build variant, so it costs one CI job rather than two.

test(e2e): Port React Router v5 and v6 E2E apps to span streaming
801356c
Removes the `traceLifecycle: 'static'` pin from `react-router-5`,
`react-router-6`, `react-router-6-use-routes` and
`react-router-6-descendant-routes`, and rewrites their specs against streamed
span v2.
The `react-router-6` SSE spec needed more than a helper swap: streamed
`http.client` names carry only the domain, so the request is matched on
`url.full`, and the abort error is read off the console because spans carry no
breadcrumbs. All three SSE tests load the same route, so each one also pins its
lookup to a pageload span that started after it navigated.

test(e2e): Port React Router SPA E2E apps to span streaming (#23843)

Ports `react-router-7-spa`, `react-router-8-spa`,
`react-router-7-cross-usage`, `react-router-8-cross-usage` and
`react-router-8-cloudflare` to span streaming.
## Why
Span streaming is the default now, so the E2E suite has to exercise it.
The Cloudflare mysql spec matches on `db.query.text`, because a streamed
mysql span is named after its query summary and both queries in that
route come out as `SELECT`.

What
Ports react-create-browser-router, react-create-hash-router and react-create-memory-router to span streaming.
Why
Span streaming is the default now, so the E2E suite has to exercise it. Two attribute groups moved and the assertions follow them: the navigator data is now device.memory.estimated_capacity, device.processor_count and network.connection.effective_type, and the pageload timings are browser.performance.*. LCP is streamed as its own ui.webvital.lcp span once the page hides, so it is no longer asserted on the pageload span.

test(e2e): Add a static trace lifecycle React Router E2E app
436f969
Copies `react-router-7-framework` into `react-router-7-framework-static`, which
keeps `traceLifecycle: 'static'` and its transaction-based specs. The rest of the
React Router group moves to span streaming in the PRs above, so this copy is what
keeps the static lifecycle covered.
The copy drops the `latest` build variant, so it costs one CI job rather than two.

test(e2e): Port React Router v5 and v6 E2E apps to span streaming
801356c
Removes the `traceLifecycle: 'static'` pin from `react-router-5`,
`react-router-6`, `react-router-6-use-routes` and
`react-router-6-descendant-routes`, and rewrites their specs against streamed
span v2.
The `react-router-6` SSE spec needed more than a helper swap: streamed
`http.client` names carry only the domain, so the request is matched on
`url.full`, and the abort error is read off the console because spans carry no
breadcrumbs. All three SSE tests load the same route, so each one also pins its
lookup to a pageload span that started after it navigated.

test(e2e): Port React Router SPA E2E apps to span streaming (#23843)
5723654
## What
Ports `react-router-7-spa`, `react-router-8-spa`,
`react-router-7-cross-usage`, `react-router-8-cross-usage` and
`react-router-8-cloudflare` to span streaming.
## Why
Span streaming is the default now, so the E2E suite has to exercise it.
The Cloudflare mysql spec matches on `db.query.text`, because a streamed
mysql span is named after its query summary and both queries in that
route come out as `SELECT`.

test(e2e): Port React Router SPA E2E apps to span streaming (#23843)
5723654
## What
Ports `react-router-7-spa`, `react-router-8-spa`,
`react-router-7-cross-usage`, `react-router-8-cross-usage` and
`react-router-8-cloudflare` to span streaming.
## Why
Span streaming is the default now, so the E2E suite has to exercise it.
The Cloudflare mysql spec matches on `db.query.text`, because a streamed
mysql span is named after its query summary and both queries in that
route come out as `SELECT`.

What
Ports react-create-browser-router, react-create-hash-router and react-create-memory-router to span streaming.
Why
Span streaming is the default now, so the E2E suite has to exercise it. Two attribute groups moved and the assertions follow them: the navigator data is now device.memory.estimated_capacity, device.processor_count and network.connection.effective_type, and the pageload timings are browser.performance.*. LCP is streamed as its own ui.webvital.lcp span once the page hides, so it is no longer asserted on the pageload span.

test(e2e): Add a static trace lifecycle React Router E2E app
436f969
Copies `react-router-7-framework` into `react-router-7-framework-static`, which
keeps `traceLifecycle: 'static'` and its transaction-based specs. The rest of the
React Router group moves to span streaming in the PRs above, so this copy is what
keeps the static lifecycle covered.
The copy drops the `latest` build variant, so it costs one CI job rather than two.
@andreiborza
test(e2e): Port React Router v5 and v6 E2E apps to span streaming
801356c
Removes the `traceLifecycle: 'static'` pin from `react-router-5`,
`react-router-6`, `react-router-6-use-routes` and
`react-router-6-descendant-routes`, and rewrites their specs against streamed
span v2.
The `react-router-6` SSE spec needed more than a helper swap: streamed
`http.client` names carry only the domain, so the request is matched on
`url.full`, and the abort error is read off the console because spans carry no
breadcrumbs. All three SSE tests load the same route, so each one also pins its
lookup to a pageload span that started after it navigated.
@andreiborza
test(e2e): Port React Router data router E2E apps to span streaming
a3cd640
Removes the `traceLifecycle: 'static'` pin from `react-create-browser-router`,
`react-create-hash-router` and `react-create-memory-router`, and rewrites their
specs against streamed span v2.
Two attribute groups moved under streaming and the assertions follow them: the
navigator data is now `device.memory.estimated_capacity`,
`device.processor_count` and `network.connection.effective_type`, and the
pageload timings are `browser.performance.*`. LCP is streamed as its own
`ui.webvital.lcp` span once the page hides, so it is no longer asserted on the
pageload span.

test(e2e): Port React Router data router E2E apps to span streaming
a3cd640
Removes the `traceLifecycle: 'static'` pin from `react-create-browser-router`,
`react-create-hash-router` and `react-create-memory-router`, and rewrites their
specs against streamed span v2.
Two attribute groups moved under streaming and the assertions follow them: the
navigator data is now `device.memory.estimated_capacity`,
`device.processor_count` and `network.connection.effective_type`, and the
pageload timings are `browser.performance.*`. LCP is streamed as its own
`ui.webvital.lcp` span once the page hides, so it is no longer asserted on the
pageload span.

test(e2e): Port React Router SPA E2E apps to span streaming (#23843)
5723654
## What
Ports `react-router-7-spa`, `react-router-8-spa`,
`react-router-7-cross-usage`, `react-router-8-cross-usage` and
`react-router-8-cloudflare` to span streaming.
## Why
Span streaming is the default now, so the E2E suite has to exercise it.
The Cloudflare mysql spec matches on `db.query.text`, because a streamed
mysql span is named after its query summary and both queries in that
route come out as `SELECT`.

test(e2e): Add a static trace lifecycle React Router E2E app
436f969
Copies `react-router-7-framework` into `react-router-7-framework-static`, which
keeps `traceLifecycle: 'static'` and its transaction-based specs. The rest of the
React Router group moves to span streaming in the PRs above, so this copy is what
keeps the static lifecycle covered.
The copy drops the `latest` build variant, so it costs one CI job rather than two.
@andreiborza
test(e2e): Port React Router v5 and v6 E2E apps to span streaming
801356c
Removes the `traceLifecycle: 'static'` pin from `react-router-5`,
`react-router-6`, `react-router-6-use-routes` and
`react-router-6-descendant-routes`, and rewrites their specs against streamed
span v2.
The `react-router-6` SSE spec needed more than a helper swap: streamed
`http.client` names carry only the domain, so the request is matched on
`url.full`, and the abort error is read off the console because spans carry no
breadcrumbs. All three SSE tests load the same route, so each one also pins its
lookup to a pageload span that started after it navigated.

test(e2e): Add a static trace lifecycle React Router E2E app
436f969
Copies `react-router-7-framework` into `react-router-7-framework-static`, which
keeps `traceLifecycle: 'static'` and its transaction-based specs. The rest of the
React Router group moves to span streaming in the PRs above, so this copy is what
keeps the static lifecycle covered.
The copy drops the `latest` build variant, so it costs one CI job rather than two.

test(e2e): Port React Router v5 and v6 E2E apps to span streaming
801356c
Removes the `traceLifecycle: 'static'` pin from `react-router-5`,
`react-router-6`, `react-router-6-use-routes` and
`react-router-6-descendant-routes`, and rewrites their specs against streamed
span v2.
The `react-router-6` SSE spec needed more than a helper swap: streamed
`http.client` names carry only the domain, so the request is matched on
`url.full`, and the abort error is read off the console because spans carry no
breadcrumbs. All three SSE tests load the same route, so each one also pins its
lookup to a pageload span that started after it navigated.

test(e2e): Port React Router data router E2E apps to span streaming
a3cd640
Removes the `traceLifecycle: 'static'` pin from `react-create-browser-router`,
`react-create-hash-router` and `react-create-memory-router`, and rewrites their
specs against streamed span v2.
Two attribute groups moved under streaming and the assertions follow them: the
navigator data is now `device.memory.estimated_capacity`,
`device.processor_count` and `network.connection.effective_type`, and the
pageload timings are `browser.performance.*`. LCP is streamed as its own
`ui.webvital.lcp` span once the page hides, so it is no longer asserted on the
pageload span.

test(e2e): Port React Router SPA E2E apps to span streaming (#23843)
5723654
## What
Ports `react-router-7-spa`, `react-router-8-spa`,
`react-router-7-cross-usage`, `react-router-8-cross-usage` and
`react-router-8-cloudflare` to span streaming.
## Why
Span streaming is the default now, so the E2E suite has to exercise it.
The Cloudflare mysql spec matches on `db.query.text`, because a streamed
mysql span is named after its query summary and both queries in that
route come out as `SELECT`.
Part of #23798
