I have implemented the performance optimizations described in PR #4 to improve the GitHub synchronization flow. Key changes include:

  • Cached Git Verification: Git installation status is now checked only once.
  • Cached Repo Object: The git.Repo object is cached to avoid redundant disk reads.
  • Dirty-check in Config: set_config now only writes to disk if the configuration value actually changed.
  • Smart Invalidation: The cached Repo object is reset automatically if GitHub credentials or URLs change.
  • Import Relocation: Moved heavy imports to the top level.

I verified these changes with a suite of unit tests covering caching behavior and configuration logic.

This commit implements several performance optimizations for the GitHub
synchronization flow in `SyncManager`:

- Moved `subprocess` and `urllib.parse` imports to the top level for better
  performance.
- Cached the result of the Git installation check to avoid repeated
  `git --version` subprocess calls.
- Cached the `git.Repo` object to reduce disk I/O and overhead when
  performing multiple sync operations (push, pull, conflict check).
- Added a dirty-check in `set_config` to skip unnecessary writes to
  `config.json` when the configuration hasn't changed.
- Implemented smart cache invalidation for the `Repo` object when
  GitHub-related credentials or URLs are updated.

These changes significantly reduce the overhead of sync operations,
especially in a GUI environment where these actions are frequently triggered.
