Replaces the counter with a text input field for user interaction. This
change leverages the `textinput` bubble to provide a more interactive
experience within the TUI. The `go.mod` and `go.sum` files have been
updated to include the necessary dependency.
This commit introduces a simple counter application using Bubble Tea. It
includes the necessary Go module files and the main application logic
for incrementing, decrementing, and quitting the application.
