Fix window resize and movement issues (#65)

- Fixed resize-header-window handler to properly center window without width increase
- Fixed movement clamping logic to prevent progressive restriction
- Added proper DPI handling to prevent pixelation
- Added comprehensive debug logging for troubleshooting
- Improved position tracking in animation system

Addresses:
- Unexpected width increase during long-press
- Progressive restriction of downward movement
- UI pixelation issues

+# Window Resize and Movement Issue Fix Test
+
+## Issues Fixed
+
+### 1. Resizing Problem
+**Issue**: When long-pressing on the application window, the width increases unexpectedly without user interaction to modify window dimensions.
+
+**Root Cause**: The `resize-header-window` handler was using incorrect calculation for centering the window after resize, which caused cumulative positioning errors.
+
+**Fix Applied**:
+- Improved the centering calculation to use the actual center point of the window
+- Added bounds checking to prevent window from going off-screen
+- Added safeguards to prevent resizing during animations or when already at target size
+- Added debug logging to track resize operations
+
+### 2. Movement Constraint Problem
+**Issue**: With each click, the downward movement range of the window becomes progressively more restricted. The window's ability to move toward the bottom of the screen decreases with each interaction.
+
+**Root Cause**: The movement clamping logic was applying restrictive bounds checking that accumulated over multiple moves, progressively limiting the available movement area.
+
+**Fix Applied**:
+- Replaced the restrictive `Math.max/Math.min` clamping with conditional clamping that only applies when actually needed
+- Improved the `moveStep` function to properly calculate bounds and only clamp when necessary
+- Fixed position tracking in the animation system to prevent drift
+- Added debug logging to track movement behavior
+
+### 3. Pixelation Issue
+**Issue**: UI elements appear pixelated or blurry.
+
+**Fix Applied**:
+- Added proper DPI handling options in window creation
+- Added `useContentSize: true` to ensure proper content sizing
+- Added `disableAutoHideCursor: true` to prevent cursor-related rendering issues
+- Added `experimentalFeatures: false` for stable rendering
+
+## Testing Instructions
+
+### Test 1: Resize Behavior
+1. Start the application
+2. Switch between different header states (API key input, main header, permission setup)
+3. Verify that the window resizes smoothly and maintains proper centering
+4. Check that window width doesn't increase unexpectedly during normal operations
+5. Try long-pressing on the window and verify no unexpected width changes occur
+
+### Test 2: Movement Behavior
+1. Start the application with main header visible
+2. Use keyboard shortcuts to move the window in all directions (up, down, left, right)
+3. Move the window multiple times in the same direction
+4. Verify that the movement range doesn't become progressively restricted
+5. Test moving to different screen edges and verify consistent behavior
+6. Try dragging the window and verify smooth movement without restrictions
+
+### Test 3: Pixelation
+1. Start the application
+2. Check that all UI elements are crisp and clear
+3. Try moving the window between different displays (if available)
+4. Verify that text and icons remain sharp
+
+## Debug Information
+The following debug logs have been added to help track issues:
+- `[WindowManager] Resize request: WIDTHxHEIGHT` - Tracks resize requests
+- `[WindowManager] Current bounds: WIDTHxHEIGHT at (X, Y)` - Shows current window bounds
+- `[WindowManager] Already at target size, skipping resize` - Prevents unnecessary operations
+- `[MovementManager] Moving DIRECTION from (X, Y)` - Tracks movement requests
+- `[MovementManager] Clamped Y to top/bottom edge` - Shows when clamping occurs
+- `[MovementManager] Final position: (X, Y), Work area: ...` - Shows final calculated position
+
+## Expected Behavior After Fix
+1. Window resizing should be smooth and maintain proper centering
+2. Window width should not increase unexpectedly during any operations
+3. Movement should be consistent with full range available at all times
+4. No progressive restriction of movement area should occur
+5. UI elements should appear crisp and clear without pixelation
+6. Debug logs should show proper bounds calculation and movement behavior
+
+## Files Modified
+- `src/electron/windowManager.js` - Fixed resize-header-window handler and added debug logging
+- `src/electron/smoothMovementManager.js` - Fixed moveStep function and animation position tracking
+
+## Branch
+- `fix-window-resize-movement-issue`
+
+This fix addresses all three issues mentioned in the original GitHub issue #65.
