chore(contact-center): trigger next npm publish

COMPLETES WXCC-6026

This pull request addresses

Deploy CD on next previously published npm packages successfully, but Publish - Tags failed because git tag v3.12.0-next.179 already existed on the remote (re-run collision). Answer on Webex SDK work is already on next; consumers need a fresh next publish and tag without re-running a failed pipeline.

Merging a minimal change under @webex/contact-center re-triggers Deploy CD: changed-package detection → version increment on the next dist-tag (e.g. 3.12.0-next.180) → npm publish for @webex/contact-center and the webex meta-package → new git tag.

by making the following changes

• Update packages/@webex/contact-center/ai-docs/contact-center-spec.md
  • Bump spec updated_at metadata to 2026-08-21
  • Add Answer on Webex to the Overview feature list (Accept, Decline, Mute, DTMF via enableWxBetterTogether)

No runtime or API changes. Documentation-only touch to satisfy changed-package detection for the CC workspace.

Change Type

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update
• Tooling change
• Internal code refactor

The following scenarios were tested

• Documentation-only change; no unit or integration test updates required.
• Verified locally that only contact-center-spec.md is modified.
• Post-merge verification (owner): confirm Deploy CD Publish - NPM and Publish - Tags succeed, then check:
  • npm view webex dist-tags.next
  • npm view @webex/contact-center dist-tags.next
