docs: Fix separator mixing contradictions across docs (bearcove#59)

The primer, quiz, landing page, audit, and Claude skill docs all
had stale references saying objects must use one separator style
consistently. The parser spec (r[object.separators]) and the
separator rules section already allowed mixing commas and newlines.

Updated all five files to be consistent. Fixes bearcove#58.

 ## Common Mistakes
 
-**Wrong**: Mixing separators in objects
-```styx
-// WRONG - can't mix newlines and commas
-server {
-    host localhost, port 8080
-}

-**Right**: Pick one separator style per block.
-
 **Wrong**: Space around `=` in attributes
 ```styx
