Draft for the fxtr 0.2.0a0 and behaviors 0.0.1a5 release. Merge after both packages are available on PyPI and the released bundle passes the content comparison against this draft.

• The behaviors skill now directs readers to guides for simulated users, checkpointing, model providers, and provider-specific sampling and caching options.
• The renderer reference explains rebuilding custom renderers for view API 4 and passing JSON parameters to entity views. The conversation guide shows how to link to a selected message.

Generated by pnpm sync:plugin from the clean main snapshot 052f907cc35979930fda832a71aec0c2194e7e48, before the package version bumps. All three skills record that source commit.
