refactor: externalize navigation handlers and fix hyperscript syntax errors

Browse Source 
- Created keyboard._hs as reference documentation (inline handler in body tag)
- Externalized 9 hamburger menu navigation links to scrollToSection()
- Added scrollToSection() as JavaScript function (CSP-safe, no eval needed)
- Restored original keyboard handler format in body tag (working correctly)
- Removed problematic navigation._hs (had syntax/CSP issues)
- Added Rule 4 to HYPERSCRIPT-RULES.md on event handler externalization
- Updated PROJECT-MEMORY.md with externalization guidelines

Key learnings:
- Complex event handlers that inspect event properties must stay inline
- JavaScript functions avoid CSP unsafe-eval restrictions
- Navigation successfully externalized: 9 links → 1 function (91% reduction)

### 2.1. Hyperscript Event Handler Externalization (2025-11-20)
**Rule: Complex event handlers that inspect event properties MUST stay inline**
**✅ CAN Be Externalized:**
- Simple navigation handlers (scrollToSection)
- Toggle handlers (toggleCVLength, toggleIcons)
- Hover sync handlers (syncPdfHover, syncPrintHover)
**❌ MUST Stay Inline:**
- Keyboard handlers that inspect `event.key`, `event.target`, modifier keys
- Event handlers with complex conditional logic based on event properties
**Why:** The `event` variable in `_=""` attributes is a hyperscript runtime variable. External `def` functions don't have direct access to this event context from HTML attributes.
**Optimization for Inline:** Use `then` chains to make compact:
```hyperscript
-- Compact inline handler with then chains
if event.key is '?' and not event.ctrlKey and not isInputField
halt the event then set modal to #shortcuts-modal then if modal then call modal.showModal() end
end
```
**Example - Navigation (Externalized):**
```html
<!-- Clean HTML - 9 navigation links use single function -->
<a href="#education" _="on click call scrollToSection(event, 'education')">
```
```hyperscript
-- External function in navigation._hs
def scrollToSection(event, sectionId)
call event.preventDefault()
set element to document.getElementById(sectionId)
if element then call element.scrollIntoView({behavior: 'smooth'}) end
end
```
**Example - Keyboard Handler (Inline):**
```html
<!-- Must stay inline - inspects event.key, event.target, modifiers -->
<body _="on keydown
set tagName to event.target.tagName
set isInputField to (tagName is 'INPUT' or tagName is 'TEXTAREA')
if event.key is 'l' and not event.ctrlKey and not isInputField
halt the event then -- handler logic
end
end">
```
**Files:**
- `static/hyperscript/navigation._hs` - External navigation function
- `templates/partials/navigation/hamburger-menu.html` - 9 clean navigation links
- `templates/index.html` - Optimized inline keyboard handler (body tag)
**Test:** `tests/mjs/2-keyboard-shortcuts.test.mjs` (keyboard shortcuts)
**Reference:** `doc/4-HYPERSCRIPT-RULES.md` Section "Rule 4: Event Handler Externalization Guidelines"

### Rule 4: Event Handler Externalization Guidelines (2025-11-20)
**Know what CAN and CANNOT be externalized**
#### ✅ **CAN Be Externalized:**
**Simple function calls without complex event inspection:**
```html
<!-- Navigation handlers -->
<a href="#section" _="on click call scrollToSection(event, 'section')">
<!-- Toggle handlers -->
<input _="on change call toggleCVLength(my.checked)">
<!-- Hover handlers -->
<button _="on mouseenter call syncPdfHover(true)
on mouseleave call syncPdfHover(false)">
```
**External function example:**
```hyperscript
def scrollToSection(event, sectionId)
call event.preventDefault()
set element to document.getElementById(sectionId)
if element then call element.scrollIntoView({behavior: 'smooth'}) end
end
```
#### ❌ **MUST Stay Inline:**
**Complex event handlers that inspect event properties:**
```html
<!-- Keyboard handlers with event.key, event.target inspection -->
<body _="on keydown
set tagName to event.target.tagName
set isInputField to (tagName is 'INPUT' or tagName is 'TEXTAREA')
if event.key is 'l' and not event.ctrlKey and not isInputField
halt the event
-- handler logic here
end
end">
```
**Why:** The `event` variable in `_=""` attributes is a hyperscript runtime variable. External `def` functions don't have direct access to this event context, causing scoping issues.
#### 🎯 **Optimization for Inline Handlers:**
**Use `then` chains to make inline code more compact:**
```hyperscript
-- Before (verbose)
if condition
do step1
do step2
do step3
end
-- After (compact with then chains)
if condition
do step1 then do step2 then do step3
end
```
**Example from body keyboard handler:**
```html
if event.key is '?' and not event.ctrlKey and not event.metaKey and not event.altKey and not isInputField
halt the event then set modal to #shortcuts-modal then if modal then call modal.showModal() end
end
```
