[wrangler] Stop publishing build metafile

[james-elicx]

Wrangler's tsup build generated wrangler-dist/metafile-cjs.json, even though no repository tooling consumes it. Because the entire wrangler-dist directory is published, this build-analysis artifact was included in every npm package.

Disable the unused metafile output so it is never generated in the publish directory.

Measured with pnpm pack before and after the change:

Metric	Before	After	Saving
Unpacked package	64.214 MiB	61.101 MiB	3.113 MiB (4.85%)
npm tarball	10.550 MiB	10.404 MiB	149.7 KiB (1.39%)
Published files	48	47	1 file

A patch changeset is included for the reduction in Wrangler's published package size.

---

• Tests
  • Tests included/updated
  • Automated tests not possible - manual testing has been completed as follows:
    • Built Wrangler with pnpm run build --filter wrangler.
    • Packed Wrangler before and after with pnpm pack --json and inspected the tarball contents.
    • Ran node packages/wrangler/bin/wrangler.js --version as a smoke test.
    • Ran oxfmt and oxlint against packages/wrangler/tsup.config.ts.
  • Additional testing not necessary because:
• Public documentation
  • Cloudflare docs PR(s):
  • Documentation not necessary because: this only removes an unused build-analysis artifact from the npm package.
