What and why:
User usually don't know what to do when they use CraftBot, so this PR is made to ease that. Ship two user-facing additions that make CraftBot faster to set up and easier to drive. Agent profile lets users export/ save / import / overwrite their full agent setup as a portable bundle, so they can clone a working agent across machines or reset cleanly without losing Living UI work. Playbooks adds a catalog of prewritten prompts users can browse and send to chat in one click.

Features / items added:

1. Agent profile export / import as a bundle (personality files, skills, MCP servers, Living UI apps)
2. New repo for hosting agent bundles (https://github.com/CraftOS-dev/craftbot-agent-bundles)
3. Living-UI-safe reset on import so prior projects aren't destroyed
4. New Playbooks button in the top bar that opens a catalog of platbooks
5. 121 curated playbooks across 19 categories (Sales, Engineering, Marketing, Health, Legal, Investing, Content, Customer Success, etc.) with search + tag filtering (28 canonical tags)
6. One-click "Use this playbook" button that drops the prewritten prompt into the chat input via a new Redux chatInputSlice
