feat(skills): add cloudflare-temporary-deploy optional skill (#50849)

* chore: re-trigger CI (workflows did not dispatch on prior head)

* feat(skills): add cloudflare-temporary-deploy optional skill

Optional web-development skill teaching the agent to deploy a Worker to a
live workers.dev URL with no Cloudflare account via 'wrangler deploy
--temporary' (Wrangler 4.102.0+). Cloudflare provisions a throwaway,
claimable account valid for 60 minutes — ideal for an autonomous
write->deploy->verify loop with no OAuth/signup hard stop.

- SKILL.md: when/when-not, prereqs (unauth requirement, version floor),
  step-by-step deploy + verify flow, product limits table, pitfalls
  (hidden flag, stale global wrangler, auth-present error, rate limits,
  workers.dev edge cache), verification.
- scripts/parse_deploy_output.py: stdlib-only parser extracting live URL,
  claim URL, account name/state, expiry, deploy status from wrangler output.
- tests/skills/test_cloudflare_temporary_deploy_skill.py: 16 tests incl.
  a real-output regression case.

Verified live end-to-end: temporary account created with no creds,
deployed to a live URL, curl confirmed body, redeploy reused the account.
