Add configurable auto-resolution for log conflicts

[tiagoarroz]

Summary

Automatically resolves sync conflicts in the plugin log file by keeping the local version, with a setting to enable or disable the behavior.

Details

• Detects conflicts for .obsidian/github-sync.log before showing the conflict resolution UI.
• Adds a local-content resolution for those log conflicts and uploads that local version as part of the sync.
• Leaves non-log conflicts in the existing conflict handling flow.
• Keeps automatic overwrite strategies working on the remaining non-log conflicts.

Validation

• Ran pnpm run build successfully.

Hey there. Thanks for the great work in this plugin.

I was running into issues with it as I want logging active but at the same time it was always creating conflicts in the logging files that I would have to resolve to sync.
I decided to add this contribution with an optional automatic conflict handling in the logging files.
