Description

This PR improves the version checking mechanism in the client-stats plugin by directly querying the installed binary instead of relying on a version file. This change makes the version checking more reliable and eliminates potential synchronization issues between the version file and the actual installed binary.

Changes

• Added new getCurrentVersion() function to directly query the binary version
• Removed version file storage mechanism
• Updated upgrade function to use actual binary version
• Improved error handling for cases where binary doesn't exist or version can't be determined

Testing

• Verified version checking works with installed binary
• Tested upgrade flow with different version scenarios
• Confirmed proper handling of non-existent binary case

Impact

This change improves reliability of the version checking system and eliminates a potential source of version mismatch errors. No breaking changes to the plugin's functionality.

Type of Change

• Enhancement (non-breaking change that adds functionality)
• Bug fix (non-breaking change that fixes an issue)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
