fix: manual release runs should version pending changesets and always re-deploy (#1394)

## Summary

Manually `workflow_dispatch`-ing this workflow to test `deploy-cdn`
(against a non-release commit - no pending changeset, no version bump)
surfaced `create-release-from-tags` throwing `No git tags found`, since
`changeset publish` correctly produced zero new tags (nothing new to
publish). That's an expected outcome for a no-op release run, not a
failure - it now logs and returns instead of throwing.

`Deploy to CDN` never got a chance to run in that failed run, since it
depends on `publish` succeeding - this fix is what actually lets
`deploy-cdn` run on a manual dispatch that isn't a real version bump, so
the current build gets re-uploaded to the CDN.

## What this PR does NOT do (reverted from an earlier version)

An earlier version of this PR also had a manual `workflow_dispatch` run
version pending changesets directly and push a "Version Packages" commit
straight to `master`, bypassing PR review. That was wrong: a release
should be a read-only operation against a commit already on `master` -
tag it, publish it to npm, cut a GitHub release, deploy it to the CDN -
never a vehicle for landing new code (a version bump is a code change
and belongs in a reviewed PR like every other change). That step has
been removed.

The correct fix for "how does a new version actually get released" is
making the normal, reviewed path work again: `release-creator.yml` opens
a "Version Packages" PR for pending changesets, someone reviews and
merges it, and *that* merge is the commit a release tags and publishes.

## Separately found, not fixed here

`release-creator.yml` (opens the "Version Packages" PR) has failed with
`startup_failure` on every run since at least 2026-07-16 - 0 jobs run,
consistent with a workflow-level rejection rather than a step failure.
Strong suspicion: `changesets/action@a45c4d594` is a third-party action,
likely hitting the same allowed-actions restriction fixed for
`aws-actions/configure-aws-credentials` in #1393. Fixing that is the
actual path to cutting new releases again - not addressed in this PR.

## Test plan

- [x] `scripts/create-release-from-tags/__tests__/index.test.ts` still
passes
- [x] `tsc` clean on the modified script (pre-push hook)
- [ ] Manual `workflow_dispatch` run against current `master` (no
pending version bump) completes `publish` and `deploy-cdn` without error
