Fix specify-rules.mdc format for Cursor IDE #669
Description
The generated specify-rules.mdc file does not follow Cursor project rules formatting guidelines. Without the cursor-rules header, the rule type defaults to "manual", meaning that agent chats won't have the top-level rule included in their contexts unless the user manually includes this.
It's possible the integration with Cursor could get better with smarter use of their rule-types (imagine auto-including test-related rules when a *-test.js file is added to chat).
In any case, the fix is easy enough that I think it should be included in the next release. Just prepend the specify-rules.mdc with a header like this:
