Important Changes

• feat(browser): Add afterStartPageloadSpan hook to improve spanId assignment on web vital spans (#16893)

This PR adds a new afterStartPageloadSpan lifecycle hook to more robustly assign the correct pageload span ID to web vital spans, replacing the previous unreliable "wait for a tick" approach with a direct callback that fires when the pageload span becomes available.

• feat(nextjs): Client-side parameterized routes (#16934)

This PR implements client-side parameterized routes for Next.js by leveraging an injected manifest within the existing app-router instrumentation to automatically parameterize all client-side transactions (e.g. users/123 and users/456 now become become users/:id).

• feat(node): Drop 401-404 and 3xx status code spans by default (#16972)

This PR changes the default behavior in the Node SDK to drop HTTP spans with 401-404 and 3xx status codes by default to reduce noise in tracing data.
