Summary

Intercept Ctrl+R/Cmd+R in before-input-event to prevent Electron default page reload
Replace hardcoded macOS shortcut symbols with platform-aware formatShortcut() helper showing Ctrl+ on Windows/Linux

Fixes #58

Changes

src/main/index.ts - Add Ctrl+R/Cmd+R intercept in existing before-input-event handler
src/renderer/utils/stringUtils.ts - Add formatShortcut(), modKey, shiftKey utilities
5 UI files - Replace hardcoded command symbols with formatShortcut() calls

Test plan

On Linux/Windows: Ctrl+R no longer reloads the Electron page
Shortcut hints show Ctrl+ instead of command symbol on non-Mac
On macOS: Cmd+R and symbols unchanged
Zoom shortcuts still work correctly

Summary by CodeRabbit

Summary of Changes

Hello @Psypeal, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses two key areas to improve the application's responsiveness and user interface consistency. It prevents the default browser-like page reload when Ctrl+R or Cmd+R is pressed, enabling custom application behavior for this shortcut. Concurrently, it standardizes the display of keyboard shortcuts across platforms, ensuring that users see the correct modifier keys for their operating system.

Highlights

Prevented Electron Page Reload: Intercepted Ctrl+R/Cmd+R key presses in the main process to prevent Electron's default page reload behavior, allowing the renderer process to handle it for application-specific actions like 'Refresh Session'.
Platform-Aware Shortcut Display: Introduced new utility functions to dynamically format and display keyboard shortcuts, showing 'Ctrl+' on Windows/Linux and '⌘' on macOS, improving user experience across different operating systems.
