format: apply repo prettier (3.8.1) to the folded skills tree

963 markdown files reformatted with the repository's pinned prettier so
pnpm format:check covers the folded tree like every other repo file.

The formatter's embedded-language pass also normalized code fences
(TS semicolons, closed HTML tags in examples, lowercased CSS hex colors,
one renumbered list that skipped an index). Alphanumeric token deltas vs
the fold commit were audited file-by-file; all are formatter-equivalent
markup normalizations plus the four sanitized skills.

 **Correct (cache hit):**
 
 ```typescript
 const getUser = cache(async (uid: number) => {
-  return await db.user.findUnique({ where: { id: uid } })
-})
+  return await db.user.findUnique({ where: { id: uid } });
+});
 
 // Primitive args use value equality
-getUser(1)
-getUser(1)  // Cache hit, returns cached result
+getUser(1);
+getUser(1); // Cache hit, returns cached result
 ```
 
 If you must pass objects, pass the same reference:
 
 ```typescript
-const params = { uid: 1 }
-getUser(params)  // Query runs
-getUser(params)  // Cache hit (same reference)
+const params = { uid: 1 };
+getUser(params); // Query runs
+getUser(params); // Cache hit (same reference)
 ```
