feat: confirm no hyperscript def limit + update documentation

MAJOR FINDING: Latest hyperscript version has NO 3 def statement limit!

Test Results (tests/mjs/9-hyperscript-def-limit.test.mjs):
✅ 1 def statement - PASS
✅ 2 def statements - PASS
✅ 3 def statements - PASS
✅ 4 def statements - PASS (beyond historical limit)
✅ 5 def statements - PASS (well beyond limit)

Changes:
1. Created comprehensive def limit test
   - tests/mjs/9-hyperscript-def-limit.test.mjs
   - Tests 1, 2, 3, 4, 5 def statements
   - Verifies both parsing and function execution
   - Provides detailed analysis and recommendations

2. Updated PROJECT-MEMORY.md
   - Section 2: Changed from "NEEDS RETESTING" to "REMOVED IN LATEST VERSION"
   - Documented test findings and historical context
   - Added migration plan for hyperscript file organization
   - Updated test count to 10 systematic tests

3. Updated doc/HYPERSCRIPT-RULES.md
   - Rule 2: Removed 3 def limit warning
   - Documented historical context (Hyperscript 0.9.12 had limit)
   - New best practice: Organize by category in separate files
   - Added recommended file structure

Impact:
- Can now use unlimited def statements in hyperscript
- Enables cleaner architecture with category-based organization
- Allows migration from cv-functions.js back to hyperscript
- Better alignment with hypermedia/server-driven pattern

Next Steps:
- Create organized hyperscript file structure
- Migrate toggle functions from JavaScript to hyperscript
- Migrate hover sync functions to hyperscript
- Test each migration thoroughly

-### 2. Hyperscript Parser Limit (NEEDS RETESTING)
+### 2. Hyperscript Parser Limit (REMOVED IN LATEST VERSION ✅)
 
-**⚠️ TO VERIFY: Maximum 3 `def` statements limit with latest hyperscript version**
+**✅ CONFIRMED: NO 3 def statement limit with latest hyperscript version**
 
-**Status:** We upgraded to the LATEST hyperscript version. This limit may no longer exist.
+**Test Results (2025-11-17):** Test 9 (`tests/mjs/9-hyperscript-def-limit.test.mjs`) confirmed:
+- ✅ 1 def statement works
+- ✅ 2 def statements work
+- ✅ 3 def statements work
+- ✅ 4 def statements work (beyond historical limit)
+- ✅ 5 def statements work (well beyond limit)
 
-**TODO:** Test if the 3 `def` statement limit still applies with current version
+**Historical Context:**
+- Hyperscript 0.9.12 had a hard 3 def limit
+- Latest hyperscript version removed this limitation
+- Functions were moved to JavaScript as workaround
+- Now migrating back to hyperscript for cleaner architecture
 
-**Current solution (still recommended):** Move complex logic to JavaScript functions
+**Current Best Practice:** Organize hyperscript functions by category in separate files
 
-```javascript
-// ✅ CORRECT - JavaScript functions
-function toggleIcons(showIcons) { ... }
-function toggleCVLength(isLong) { ... }
-function toggleTheme(isClean) { ... }
-
-// Call from hyperscript
-_="on change call toggleIcons(my.checked)"
-
-// ❌ WRONG - Too many def statements
-_="def toggleIcons(show)
-     if show then add .show-icons...
-   end"
+```

 ```
 
-**Why:** Parser crashes/fails silently when limit exceeded.
+**Migration in progress:** Moving functions from `cv-functions.js` back to hyperscript
 
-**Test that enforces this:** `tests/mjs/3-hyperscript.test.mjs`
+**Test that verifies no limit:** `tests/mjs/9-hyperscript-def-limit.test.mjs`
