ci: IS-572: re-sync ported Cloudflare Workers pipeline files with rollingclaude/cf-port-circinus

The category-1 files in this port are byte-identical copies from `rolling`.
`rolling` has since moved: [vyos-documentation#2209](https://github.com/vyos/vyos-documentation/pull/2209)
merged as `3a1c6c30`, thirteen rounds of hardening on exactly these files.

Re-take all 14 category-1 paths from `origin/rolling` via
`git checkout origin/rolling -- <paths>`, so byte-identity holds by
construction rather than by hand-editing:

  .github/workflows/docs-build.yml
  scripts/docs_gates/{gates,parity,smoke,test_gates,test_parity,test_smoke}.py
  workers/.gitignore
  workers/apex/src/{index,special,uagate}.ts
  workers/apex/test/{router,uagate}.test.ts
  workers/apex/ua-policy.json

Thirteen of the fourteen carry
[vyos-documentation#2209](https://github.com/vyos/vyos-documentation/pull/2209)
exactly — the pre-change tree was byte-identical to `3a1c6c30^` for those
paths. `workers/.gitignore` additionally picks up the one-line `test-results/`
entry from
[vyos-documentation#2212](https://github.com/vyos/vyos-documentation/pull/2212);
inert on circinus, since only the deliberately-unported `apex-deploy.yml`
writes that directory.

Deliberate exclusions are unchanged: `docs-canary-qa.yml` (cron runs on the
default branch only, so it is not ported even though
[vyos-documentation#2209](https://github.com/vyos/vyos-documentation/pull/2209)
touched it on `rolling`), `apex-deploy.yml`, and the `docs-preview-*`
workflows. `docs/conf.py` stays hand-merged and circinus-specific, with its
ReadTheDocs fallback intact.
