fix(msteams): add @microsoft/agents-hosting to root dependencies

Bundled extensions ship inside the openclaw package (via the files array),
but their node_modules are not included. In global/Homebrew installs, Node
module resolution cannot find @microsoft/agents-hosting because it was only
declared in the extension's package.json and explicitly allowlisted as an
expected gap via rootDependencyMirrorAllowlist.

This commit:
- Adds @microsoft/agents-hosting ^1.3.1 to the root package.json
  dependencies so it is installed alongside openclaw in all install modes
- Clears the now-stale rootDependencyMirrorAllowlist entry in the msteams
  extension manifest so the release-check gate will catch future drift
- Updates pnpm-lock.yaml to include the new root dependency

Fixes the runtime error:
  Cannot find module '@microsoft/agents-hosting'

Supersedes #16606.
