Fix print null errors and add main process logging to renderer console

- Added null checks for toolbar, tab-bar, status-bar before accessing .style
- Prevents TypeError when elements don't exist
- Added executeJavaScript to send main process logs to renderer console
- Now we can see main process state in DevTools
- Print should now work without errors

-# Push Instructions for Pan Converter
+# Test Double-Click File Opening
 
-## Prerequisites
-1. Create a new repository on GitHub: https://github.com/new
-   - Repository name: `pan-converter`
-   - Keep it empty (no README, .gitignore, or license)
-   - Make it public or private as desired
+This is a test file to verify double-click functionality.
 
-2. Set up authentication:
-   - **Option A - SSH Key** (Recommended):
-     ```bash
-     # Check if you have SSH key
-     ls -la ~/.ssh/id_rsa.pub
+## Features to Test
+- File should load automatically
+- Content should display in editor
+- Tab should show filename
+- Preview should render markdown
 
-     # If not, generate one:
-     ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
-     
-     # Add to GitHub: Settings > SSH and GPG keys > New SSH key
-     cat ~/.ssh/id_rsa.pub
-     ```
-   
-   - **Option B - Personal Access Token**:
-     - Go to GitHub Settings > Developer settings > Personal access tokens
-     - Generate new token with 'repo' scope
-     - Save the token securely
-
-## Push Commands
-
-### Using SSH (Recommended)
-```bash
-# Set SSH remote
-git remote set-url origin git@github.com:amitwh/pan-converter.git
-
-# Push all branches
-git push -u origin master
-git push origin linux
-git push origin macos
-git push origin windows
-```
-
-### Using HTTPS with Token
-```bash
-# Set HTTPS remote
-git remote set-url origin https://github.com/amitwh/pan-converter.git
-
-# Push all branches (you'll be prompted for username and token)
-git push -u origin master
-git push origin linux
-git push origin macos
-git push origin windows
-
-# When prompted:
-# Username: amitwh
-# Password: [paste your Personal Access Token]
-```
-
-### Using GitHub CLI (if installed)
-```bash
-# Login to GitHub CLI
-gh auth login
-
-# Create repo and push
-gh repo create pan-converter --public --source=. --remote=origin --push
-```
-
-## Automated Script
-```bash
-# Run the provided script
-./push-to-github.sh
-```
-
-## Verify Success
-After pushing, verify at: https://github.com/amitwh/pan-converter
-
-You should see:
-- 4 branches (master, linux, macos, windows)
-- All project files
-- Complete commit history
-
-## Troubleshooting
-
-### Authentication Failed
-- For SSH: Ensure your SSH key is added to GitHub
-- For HTTPS: Use Personal Access Token, not password
-- Check token has 'repo' scope
-
-### Repository Not Found
-- Ensure repository exists on GitHub
-- Check spelling: `pan-converter`
-- Verify you're logged into the correct GitHub account
-
-### Permission Denied
-- Check repository ownership
-- Ensure you have write access
-- Verify authentication method is correct
