Fix HMR crash when editing content collection files in Cloudflare adapter projects using zod v4

[matthewp]

Changes

• Fixes a crash (Cannot split a chunk that has already been edited) that occurs when editing content collection files during dev in Cloudflare adapter
• Adds banner: { js: '' } to esbuildOptions in the configEnvironment hook for server environments. This suppresses the createRequire(import.meta.url) banner that Vite prepends to pre-bundled SSR chunks, which is the trigger for the collision.
• The root cause is a Vite bug (vitejs/vite#22004): Vite's SSR transform replaces import.meta at positions 69–80, then tries to also replace the meta identifier (positions 76–80) from zod v4's meta export — but those positions are already inside the edited range. The fix is merged on Vite main (vitejs/vite#22019) but not yet backported to v7.

Testing

• Manually verified
