[Docs] Add cloud agent adoption recipe

[roomote-roomote]

Created by Roomote. Follow up by mentioning @roomote-roomote, in the web UI, or in Slack.

What changed

Added a Cookbook recipe for introducing cloud agents through simple, low-risk team habits. It covers leader-led examples in #factory, codebase questions in #ask-roomote, direct custom emoji reactions, Review Code for engineer-authored PRs, read-only starter tasks, public feedback loops, and private rehearsal.

The recipe is attributed to Bruno Bergher and appears in the generated Cookbook index without being added to the sidebar. Contributor guidance now makes that navigation exception explicit, and the generator uses deterministic English title sorting.

Why this change was made

Teams may hesitate to use cloud agents in public before they understand how the work is started, reviewed, and corrected. This recipe gives installers and team leads a small adoption ladder that builds familiarity before adding autonomy.

Impact

Docs readers now have a copyable, adoption-focused playbook for helping engineers build trust in Roomote without beginning with complex automations or code-changing tasks. Future recipes follow a documented file-plus-generator workflow and remain discoverable through the alphabetized index rather than crowding the sidebar.

1 issue outstanding. See task

• apps/docs/cookbook/ease-your-team-into-cloud-agents.mdx:31 — Custom Emoji Reaction is not a configurable Roomote automation. The recipe tells readers to add and enable it, so this adoption path cannot be followed; replace it with an existing feature/workflow or document the actual setup.
• apps/docs/cookbook/ease-your-team-into-cloud-agents.mdx:48 — Simply enabling Review Code does not review PRs opened by people: reviewAllPullRequestAuthors defaults to false. Tell readers to enable Review PRs not created by Roomote as well, otherwise the recommended human-PR review stage never runs.
• apps/docs/cookbook/ease-your-team-into-cloud-agents.mdx:83 — The reaction prompt says the target message is “linked below,” but no message link or placeholder follows. The supported action needs the Slack channel and message timestamp, so this copyable prompt cannot be completed as written; include a Slack message permalink or an explicit placeholder for one.

Updated in 975999b: removed the recipe from sidebar navigation, documented the file-plus-generator Cookbook workflow, pinned deterministic title sorting, and corrected the custom-reaction and Review Code setup guidance. The draft PR body and screenshots now reflect the shipped result.
