chore(wrangler): use the unenv preset from @cloudflare/unenv-preset

[vicb]

The cloudflare preset was migrated to this mono-repo (@cloudflare/unenv-preset)

This PR is switching to using this version

To do before merging:

• diff the output of a wrangler build before/after
• test the pre-release version of wrangler
• [ ] make sure the Vite plugin works with @cloudflare/unenv-preset (from discussion with @vicb and @petebacondarwin : not actually needed for this PR as it doesn't touch vite plugin)
• publish @cloudflare/unenv-preset@1.0.0 and use that version

/cc @petebacondarwin @pi0 @dario-piotrowicz

• Tests
  • TODO (before merge)
  • Tests included
  • Tests not necessary because: preset is tested, will do a diff test
• E2E Tests CI Job required? (Use "e2e" label or ask maintainer to run separately)
  • I don't know
  • Required
  • Not required because:
• Public documentation
  • TODO (before merge)
  • Cloudflare docs PR(s):
  • Documentation not necessary because: no user facing change

wrangler@3.102.0 includes the following runtime dependencies:

Package	Constraint	Resolved
miniflare	workspace:*	3.20241230.2
workerd	1.20241230.0	1.20241230.0
workerd --version	1.20241230.0	2024-12-30

Please ensure constraints are pinned, and miniflare/workerd minor versions match.

I generated https://github.com/opennextjs/opennextjs-cloudflare/tree/main/examples/vercel-blog-starter with both wrangler 3.101.0 and a dev version of wrangler built from this PR to see if there are any differences.

The differences are:

Better names

// stable
// ../../../../../.nvm/versions/node/v22.11.0/lib/node_modules/wrangler/_virtual_unenv_global_polyfill-clear$immediate.js
var init_virtual_unenv_global_polyfill_clear_immediate = __esm({
  "../../../../../.nvm/versions/node/v22.11.0/lib/node_modules/wrangler/_virtual_unenv_global_polyfill-clear$immediate.js"() {
    init_cloudflare();
    globalThis.clearImmediate = clearImmediateFallback;
  }
});

// dev
// ../../../workers-sdk/packages/wrangler/_virtual_unenv_global_polyfill-clear$immediate.js
var init_virtual_unenv_global_polyfill_clear_immediate = __esm({
  "../../../workers-sdk/packages/wrangler/_virtual_unenv_global_polyfill-clear$immediate.js"() {
    init_timers();
    globalThis.clearImmediate = clearImmediateFallback;
  }
});

init_timers is better than init_cloudflare (we end up having init_cloudflare2, init_cloudflare3, init_cloudflare4, ... for all the $cloudflare.ts file

Path are different (expected)

// Stable
// ../../../../../.nvm/versions/node/v22.11.0/lib/node_modules/wrangler/node_modules/unenv/runtime/node/timers/internal/immediate.mjs
var Immediate;
var init_immediate = __esm({
  "../../../../../.nvm/versions/node/v22.11.0/lib/node_modules/wrangler/node_modules/unenv/runtime/node/timers/internal/immediate.mjs"() {
    init_virtual_unenv_global_polyfill_process();
    
// Dev
// ../../../workers-sdk/node_modules/.pnpm/unenv-nightly@2.0.0-20241218-183400-5d6aec3/node_modules/unenv-nightly/runtime/node/timers/internal/immediate.mjs
var Immediate;
var init_immediate = __esm({
  "../../../workers-sdk/node_modules/.pnpm/unenv-nightly@2.0.0-20241218-183400-5d6aec3/node_modules/unenv-nightly/runtime/node/timers/internal/immediate.mjs"() {

So no functional changes between the current (stable) and PR state.

It is pleasing that you didn't need to change much inside Wrangler to get this to work.

True - but this change was prepared in #7721, #7697, #7685, #7625, #7522, and a few other PRs :)

[petebacondarwin]

Don't we want to lock this down to a specific version?
Similar to the unenv, miniflare and workerd versions we want to explicitly lock these into Wrangler, and then bump them all at the same time, right?

[vicb]

We want the latest version of the preset.
I hope that the peerDep on workerd in the preset will constrain the version (via the local workerd)
Maybe we can pin to 1.0.x or even 1.0.0 until we make sure that works correctly?

[petebacondarwin]

Interesting... I hope it works that way (for all package managers.)

[petebacondarwin]

Let's try not pinning for now and then see if it works as expected for our first few releases.
