🔧 Add setting to disable changelog popup and update notifications

Summary

This PR implements a new user setting to disable the automatic changelog popup and update notifications when the extension updates, addressing issue #56. The feature makes both the changelog popup and update notifications opt-in rather than automatic, providing a completely quiet update experience for users who prefer not to be disturbed by update-related notifications.

Changes Made

🆕 New Setting

• Added cursorStats.showChangelogOnUpdate configuration setting
• Default value: false (disabled by default to reduce distraction)
• Type: boolean
• Description: "Show changelog popup and update notifications when extension updates"
• Controls: Both changelog webview AND update notification messages

🔧 Implementation Details

1. Extension Activation (src/extension.ts)

   • Check the setting before showing changelog on extension update
   • Log appropriate messages based on user preference

2. GitHub Service (src/services/github.ts)

   • Respect the setting for both automatic update checks and specific version displays
   • Hide both changelog popup AND update notification when disabled
   • Maintain existing functionality when setting is enabled

3. Configuration (package.json)

   • Added the new setting to the extension's configuration schema
   • Placed logically with other extension settings

📚 Documentation Updates

• README.md: Added the new setting to the configuration table
• CHANGELOG.md: Documented the new feature in version 1.1.4

Behavior

When showChangelogOnUpdate is false (default):

• ✅ No changelog popup appears on extension updates
• ✅ No update notifications appear (completely quiet)
• ✅ Extension updates silently in the background
• ✅ Users can still manually view changelogs via other means

When showChangelogOnUpdate is true:

• ✅ Maintains existing behavior
• ✅ Changelog popup appears on updates as before
• ✅ Update notifications are shown as before

🌍 Internationalization

• ✅ Fully compatible with existing i18n implementation
• ✅ All user-facing strings already translated in English, Chinese, and Korean
• ✅ Configuration setting follows VS Code standard (not requiring translation)

🧪 Testing

• ✅ Code compiles without errors
• ✅ No linting issues
• ✅ Maintains backward compatibility
• ✅ Existing functionality preserved when setting is enabled

📋 Checklist

• New setting added to package.json
• Implementation respects the setting in all relevant code paths
• Documentation updated (README + CHANGELOG)
• Default value set to false (opt-in behavior)
• Backward compatibility maintained
• i18n compatibility verified
• Code quality checks passed

🔗 Resolves

Closes #56

🎯 Impact

This change significantly improves the user experience by:

• Providing a completely quiet update experience for users who don't want to be disturbed
• Making all update-related notifications opt-in rather than forced behavior
• Maintaining flexibility for users who do want to see changelogs and notifications
• Following best practices for non-intrusive extension behavior

Users can enable the setting if they want to see changelogs and update notifications, but by default, the extension will update completely silently without any interruption to the user's workflow.
