This fix addresses the critical issue where double-clicking .md files would not open them in the installed PanConverter application on Windows.
## Root Cause
When a user double-clicks a file and the app is already running, Windows tries to launch a SECOND INSTANCE with the file path. Without single-instance lock handling, that second instance would exit and the first instance would never receive the file path.
## Changes
- Added single-instance lock handling in main.js (lines 52-85)
- Implemented second-instance event handler to capture file paths
- Focus existing window when second instance is attempted
- Pass file path to existing instance using openFileFromPath()
- Properly handle rendererReady state for file opening
## Testing
- Works in development mode (npm start)
- Should now work correctly in installed Windows app with double-click
- Maintains single instance behavior across all file opening methods

Cleaned up debug logging from file opening investigation:
- Removed console.log from command line arg processing
- Removed console.log from renderer-ready handler
- Removed console.log from openFileFromPath function
- Removed console.log from file-opened IPC handler
The double-click file opening fix is confirmed working.
🤖 Generated with [Claude Code](https://claude.com/claude-code)
CRITICAL BUG FIX: Files opened via double-click were not rendering in the application.
Root Cause:
- The openFileFromPath() function was sending IPC 'file-opened' message WITHOUT checking if rendererReady was true
- When files were double-clicked before renderer initialization, the IPC message was sent but lost
- The comment "Always try to send, the renderer will handle it when ready" was incorrect
The Fix (src/main.js:1586):
- Added rendererReady check to the conditional: if (mainWindow && mainWindow.webContents && rendererReady)
- Now properly stores file in app.pendingFile when renderer is not ready
- File is opened correctly when renderer-ready signal arrives
Flow:
1. File double-clicked → openFileFromPath() called
2. If renderer NOT ready → store in app.pendingFile
3. When renderer sends 'renderer-ready' → openFileFromPath(app.pendingFile) is called
4. This time renderer IS ready → file opens successfully
