Maestrly v0.28.1–v0.29.1: Artifact pages that collect responses

This round turns artifact pages into simple forms and makes bot logins stick around.

• Collect responses on an artifact. A page can now save one response from each person who opens it, like the answers to a form you send someone. Guests type their name once before their first response.

• Ask an agent for a form. Agents know the new page API and read the responses with the artifact_responses tool, so asking one to build a form just works.

• Manage what comes in. The artifact's details list the responses, delete them and export them as CSV or JSON. Share → Responses turns them off.

• Bot browser stays open. A bot's Chromium no longer closes after 15 idle minutes, so it no longer signs the bot out of Google. It stays open until the bot pauses or its environment restarts.

• Logins survive reopens. Sites that keep their login in session cookies stay signed in when a bot's Chromium reopens after a pause or a restart.

Responses need a bot server on v0.29.0 or later. After updating, sign your bots in to Google once more.
