Verify cache key normalisation consistency across read and write paths.

The write path normalises the URL (removes trailing slashes except for root) before appending .json, whilst the read path on line 124 extracts the base URL from the payload request path. Whilst these should produce matching keys in normal cases, consider extracting the normalisation logic into a helper function to ensure consistency and prevent future drift.

Example helper:

function normalizePayloadCacheKey(url: string): string {
  const normalized = url === '/' ? '/' : url.replace(/\/$/, '')
  return normalized + '.json'
}

This would make both paths use the same logic and improve maintainability.

Additionally, run the following verification script to check for any other payloadCache operations that might need updating:

#!/bin/bash
# Description: Find all payloadCache operations to ensure complete .json migration

# Search for all payloadCache method calls
rg -n -C3 'payloadCache\s*!\s*\.\s*(setItem|getItem|hasItem|removeItem)' --type=ts

In `@packages/nitro-server/src/runtime/handlers/renderer.ts` at line 195, The
write path for payloadCache uses inline URL normalization which may diverge from
the read path; extract the normalization into a single helper (e.g.
normalizePayloadCacheKey) that takes ssrContext.url (or the incoming request
path) and returns the normalized key with the ".json" suffix, then replace the
inline logic in the write site (where renderPayloadResponse is stored via
payloadCache!.setItem) and in the read path (the code that calls
payloadCache!.getItem / hasItem / removeItem) to call this helper so both use
identical logic; also search for all payloadCache usages
(setItem/getItem/hasItem/removeItem) and update them to use the helper (you can
run the provided ripgrep script to find occurrences).
