Fix CUA mode, selection keybindings, and replace Corfu with Company

Major improvements to Emacs configuration:

1. Fixed CUA mode and C-Shift-Arrow selection issues
   - Properly configured CUA mode for copy/paste (C-c, C-v, C-x)
   - Fixed C-Shift-Arrow word selection that was being intercepted
   - Added mode-specific CUA disabling for special modes

2. Replaced Corfu with Company mode
   - Removed problematic Corfu configuration causing errors
   - Installed and configured Company for stable auto-completion
   - Set up proper completion triggers and navigation

3. Integrated standalone fix files into existing configuration
   - Merged keybinding-fix.el into relevant config files
   - Added diagnostic functions for debugging keybinding issues
   - Cleaner organization with fixes in their respective modules

4. Enhanced diagnostics
   - Added diagnose-cua-selection for CUA/selection issues
   - Added diagnose-key-conflicts for debugging key bindings
   - Emergency editing restoration functions preserved

All changes tested and verified working.

+# Configuration Integration Summary
+
+## Successfully Integrated Fix Files
+
+### 1. keybinding-fix.el → Integrated into multiple files
+- **elfeed-config.el**: Added CUA mode disabling hooks and keybinding setup for elfeed modes
+- **portfolio-tracker-v2.el**: Added CUA mode disabling in mode definition
+- **init-editor.el**: Added `diagnose-key-conflicts` function for debugging
+- **init-ui.el**: Already contains CUA mode configuration with mode-specific disabling
+
+### 2. elfeed-debug.el → Partially integrated
+- Diagnostic functionality merged into `diagnose-key-conflicts` in init-editor.el
+- Elfeed-specific fixes integrated into elfeed-config.el
+
+### 3. Removed Files
+- `/Users/jens/.emacs.d/keybinding-fix.el` - Fully integrated
+- `/Users/jens/.emacs.d/elfeed-debug.el` - Functionality integrated
+- Temporary test and documentation files removed
+
+## Retained Fix Files (Properly Organized)
+
+### In lisp/ directory:
+1. **init-emergency-fix.el** - Emergency editing restoration functions
+2. **init-eslint-fix.el** - ESLint configuration handling
+3. **init-seq-fix.el** - Seq library compatibility fixes
+
+These are legitimate fix modules that should remain as separate files.
+
+## Key Improvements
+
+1. **Cleaner Organization**: Fix code integrated into relevant configuration files
+2. **No Duplicate Loading**: Removed redundant fix file loading from init.el
+3. **Better Maintainability**: Related fixes are now with their respective modules
+
+## Verification
+✓ Configuration loads successfully
+✓ CUA mode enabled with proper settings
+✓ Company mode installed and available
+✓ Emergency fixes accessible
+✓ Diagnostic functions available
+
+## Diagnostic Commands
+- `M-x diagnose-cua-selection` - Check CUA and selection settings
+- `M-x diagnose-key-conflicts` - Debug key binding conflicts
+- `M-x diagnose-editing-issue` - Check why editing might be disabled
+- `M-x fix-editing-now` - Emergency fix for editing issues
