First official release of the Priority-Based Task Manager CLI app

This release includes these features:

• Console interface with welcome screen
• Add, update, complete, and remove tasks
• Display all tasks (ordered by priority) and clear all tasks
• In-memory storage using priority queue and vector
• Persistent storage with SQLite

Regular users: Just unzip the app bundle and run task_manager.exe from inside the bin/ folder.
Developers: Clone the repo and use the build scripts inside scripts/ to build and run.

Note: Some antivirus programs may falsely flag the executable. This is a known issue due to the nature of unsigned EXEs.
