remove: eliminate floating status panel above editor menu

Removed redundant floating status panel that appeared above the editor menu:

## 🗑️ Floating Status Panel Removal
- **Issue**: Floating status panel in top-right corner duplicated information already in menu
- **Solution**: Disabled `updateStatusDisplay()` method and removed `createStatusPanel()`
- **Result**: Cleaner UI with status information only shown in integrated menu

## 🎯 Changes Made
- **updateStatusDisplay()**: Now returns early without creating floating panel
- **createStatusPanel()**: Method removed since no longer needed
- **Status Integration**: Status information remains available in control panel menu
- **UI Cleanup**: Eliminates visual clutter and redundant information display

## 🚀 User Experience Improvements
- **Cleaner Interface**: No floating overlay competing with menu
- **Single Source**: Status information consolidated in menu only
- **Reduced Clutter**: Simpler, more focused editing experience
- **Better Performance**: No unnecessary DOM element creation/updates

## 🔧 Technical Benefits
- **Code Simplification**: Removed ~40 lines of floating panel code
- **Performance**: No periodic floating panel updates (every 2 seconds)
- **Memory Efficiency**: No floating DOM elements consuming resources
- **Maintainability**: Single status display location to maintain

## ✅ Backward Compatibility
- **Control Panel**: Status information still available in menu
- **Status Tracking**: Real-time tracking continues to work
- **Menu Integration**: All status features remain functional
- **No Functionality Loss**: Only redundant display removed

Added comprehensive test suite with 5 tests verifying floating panel removal.
Interface is now cleaner with status information properly integrated into menu.

-## Theme System Refactor Context
-
-**Current State**: Work-in-progress theme system refactor is stashed and partially complete.
-
-**Completed Parts ✅**:
-- New Layered Theme Architecture: Complete LAYERED_THEMES system with UI, document, and branding scopes
-- Theme Parsing Functions: `parse_theme_string()` and `combine_theme_properties()`
-- CSS Generation Refactor: New `_get_template_css()` and `_generate_layered_css()` methods
-- CLI Parameter Change: Changed from `--template` to `--theme` throughout test files
-- Legacy Compatibility: LEGACY_THEME_MAPPING for backward compatibility
-
-**Missing/Incomplete Parts ❌**:
-- CLI Parameter Validation: The new `--theme` parameter needs validation for invalid themes
-- Function Signature Inconsistencies: Some functions still accept `template` parameter but call it with `theme`
-- Additional Files: Other files in the codebase still use old `template` parameter
-- Error Handling: The warning system for unknown themes needs proper logging
-
-**New Capabilities When Complete**:
-- Single themes: `basic`, `github`, `dark`, `academic`, `light`, `corporate`, `startup`
-- Layered themes: `dark,academic` combines dark UI with academic typography
-- Complex combinations: `light,github,corporate` for branded GitHub-style documents
-- Legacy compatibility: Existing `--template` usage continues to work
 
 ***

+const MARKITECT_EDITOR_CONFIG = {
+    mode: 'insert',
+    restrictedHeadingLevels: [1, 2, 3],
+    // ... standard editor config
+};
+```
+
+**Section Enhancement**:
+- `Section.detectHeadingLevel()` - Identify heading levels 1-6
+- `Section.isProtectedHeading()` - Check if heading is protected in current mode
+- `Section.getHeadingText()` - Extract heading text for display
+- `Section.getHeadingContent()` - Extract content after heading for editing
+
+**Validation Logic**:
+- Pre-acceptance validation ensures protected headings remain unchanged
+- Error handling for attempted heading modifications
+- Content reconstruction maintains heading + content structure
+
+### Behavioral Differences from Edit Mode

+## Asset Management Features
+
+MarkiTect provides several key features for managing image assets:
+
+1. **Content-Addressable Storage**: Images are stored using SHA-256 hashes to prevent duplication
+2. **Automatic Deduplication**: Identical images are only stored once, regardless of filename
+3. **Relative Path Resolution**: Images can be referenced using relative paths from the markdown file
+4. **Asset Tracking**: All referenced assets are tracked and validated during document processing
+
+## Performance Metrics
+
+The following chart shows system performance over time:
