[codex] Enable Grok adapter canary publishing (#6154)

## Thinking Path

> - Paperclip publishes its CLI, server, UI, and adapter packages
through the shared release workflow.
> - Canary releases are driven by the GitHub release workflow on pushes
to `master`.
> - The release workflow does not publish every public package
automatically; it uses `scripts/release-package-manifest.json` as the CI
enrollment source of truth.
> - The Grok adapter is public and already present in the manifest, but
its `publishFromCi` flag was still disabled.
> - Because of that flag, normal canary publishes skipped
`@paperclipai/adapter-grok-local` even when the main package received a
canary.
> - This pull request enables Grok in the release manifest so future
canary runs include it.
> - The benefit is that Grok adapter canaries stay aligned with the rest
of the package release set.

## What Changed

- Set `packages/adapters/grok-local` / `@paperclipai/adapter-grok-local`
to `publishFromCi: true` in `scripts/release-package-manifest.json`.

## Verification

- `node ./scripts/release-package-map.mjs check`
- `node ./scripts/release-package-map.mjs list | grep
'@paperclipai/adapter-grok-local'`
- `pnpm test:release-registry`

## Risks

- Low risk: this is a release manifest-only change.
- Future canary releases will attempt to publish
`@paperclipai/adapter-grok-local`; this assumes the package remains
publishable and trusted publishing/package access are correctly
configured for the existing npm package.

> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.

## Model Used

- OpenAI Codex, GPT-5-based coding agent with shell, git, and GitHub
tool use.
