Adds the changeset that #14704 omitted, so that edge-preview-authenticated-proxy actually gets deployed and starts reporting Prometheus metrics again.

What's broken

The Prometheus_Rule_Failed_Checks pint alert has been firing against chat-workers-devprod. pint_problem{owner="chat-workers-devprod"} currently returns 12 series, all for this Worker and none for the other two DevProd Workers:

reporter: promql/series
kind:     recording
filename: /etc/prometheus/recording.d/global_edge_devprod.rules.yaml
name:     global:devprod_edge_preview_authenticated_proxy_error:ratio15m   (and :ratio3h)
problem:  query on nonexistent series: `edge` Prometheus server at
          https://edge.prometheus-access.cfdata.org didn't have any series for the
          `colo:devprod_edge_preview_authenticated_proxy_request:increase15m`
          metric in the last 1w.

The denominator of the SLI doesn't exist because the Worker isn't pushing any counters.

Why

• 2026-06-13 — all three DevProd Workers stop reporting; the plain fetch() to workers-logging.cfdata.org no longer works.
• 2026-07-16 — [devprod] Migrate metrics to WShim internal binding #14704 migrates edge-preview-authenticated-proxy, format-errors and playground-preview-worker to the WSHIM_SOCKET internal service binding. That PR carried no changeset.
• 2026-07-17 — chore: consolidate most packages on zod 4.4.3 in pnpm catalog #14707 (zod v4) bumps format-errors@0.0.9 and playground-preview-worker@0.3.3, which incidentally deploys them with the WShim change.
• 2026-07-18 — those two start reporting again and their pint problems clear.
• edge-preview-authenticated-proxy is still on 0.3.2, released by Internal infrastructure changes #14157 which predates the WShim change.

tools/deployments/deploy-non-npm-packages.ts only deploys packages present in PUBLISHED_PACKAGES, i.e. packages that changesets actually version-bumped. All three Workers have wrangler/@cloudflare/workers-utils as devDependencies, so changesets never bumps them automatically. No changeset means no version bump, which means no deploy — the WShim fix was merged over a month ago but has never reached production.

The change

A changeset only, no code changes. changeset status confirms @cloudflare/edge-preview-authenticated-proxy is now queued for a patch bump, which will put it into PUBLISHED_PACKAGES and trigger wrangler deploy on the next release.

Verifying after release

count(edge_preview_authenticated_proxy_devprod_edge_preview_authenticated_proxy_request_total) should become non-empty and pint_problem{owner="chat-workers-devprod"} should go empty. format-errors took ~2 days to reappear after its deploy. The alert has for: 4h, so expect it to resolve a few hours after the series returns.

One thing to watch: #14704 also added secrets.required to this Worker's wrangler.jsonc. Those become inherit bindings and the API hard-fails the deploy if any of PROMETHEUS_TOKEN, SENTRY_ACCESS_CLIENT_SECRET or SENTRY_ACCESS_CLIENT_ID is unset. All three were used by the pre-#14704 code so they should already exist, but that's the first thing to check if the deploy step fails.

• Tests
  • Tests included/updated
  • Automated tests not possible - manual testing has been completed as follows:
  • Additional testing not necessary because: this PR contains no code changes. It only adds the changeset that [devprod] Migrate metrics to WShim internal binding #14704 omitted, so the already-merged and tested code finally gets released.
• Public documentation
  • Cloudflare docs PR(s):
  • Documentation not necessary because: this is an internal Cloudflare Worker with no public API surface.
