ci: fix scripts dep coverage gap and wrong self-reference path (#373)

* ci: fix scripts dep coverage gap and wrong self-reference path

- Add scripts/** to deploy-worker.yml path triggers so dependabot PRs
  bumping ajv/ajv-formats route through validate-festivals instead of
  silently skipping all CI jobs
- Add scripts/** to the festivals path filter in the changes job so
  validate-festivals actually runs on those PRs
- Fix self-referencing path filter: was cloudflare-worker.yml (wrong
  filename), now correctly points to deploy-worker.yml

* ci: rename deploy-worker.yml to cloudflare-worker.yml

The workflow manages the full Cloudflare Worker lifecycle (test,
validate, deploy) — not just deployment. Rename to match what it
manages, consistent with how the Pages workflows are named.

Also update the workflow name field to match.
