This pull request introduces improvements to the installer script (AddToPath.iss) for better handling of PATH modifications, as well as a minor refactor in the TUI operation registry. The installer now more accurately tracks and logs when the PATH environment variable is changed or when an update fails, and only broadcasts environment changes when necessary. The TUI registry now uses a dedicated method to remove operations from the queue.

Installer script improvements:

• Added a new boolean variable UnigetPathChanged to track if the PATH was actually modified during installation (AddToPath.iss).
• Set UnigetPathChanged to True after a successful PATH update, and reset it (along with a new Failed variable) at the start of the update process (AddToPath.iss) [1] [2].
• Only broadcasts the environment change if the PATH was modified or the update failed, with improved logging and early exit if no changes occurred (AddToPath.iss).
• Added a local Failed variable to track exceptions during PATH updates (AddToPath.iss).

TUI operation registry refactor:

• Replaced inline removal loop with a call to the new AbstractOperation.RemoveFromQueue(op) method for cleaner queue management (TuiOperationRegistry.cs).
