Fixes a rendering bug where template URLs like
`https://<project-ref>.supabase.co/...` were displayed incorrectly in
Assistant responses. The markdown parser was treating `<project-ref>` as
a tag and silently stripping it.
- Adds `wrapPlaceholderUrls()` preprocessing step that auto-wraps bare
URLs containing `<kebab-case>` placeholders in backticks before passing
to the markdown renderer
- Strengthens the prompt instruction to explicitly say "always format
template URLs as inline code using backticks"
Sample prompt:
```
What are the OAuth2 endpoints for Supabase projects? List the authorization, token, and JWKS URLs.
```
