bxnotify.c: Refactor error and exit handling for suite consistency.

  - Update the cleanup() function signature to accept an integer
    error code (int err), allowing the function to terminate the
    process via exit() based on runtime success or failure.
  - Modify die() to call cleanup(1) instead of exit(1), ensuring
    all resources (X11 connections, text buffers, registry 
    positions) are properly freed even when terminating due to 
    an error.
  - Update the successful exit path in main() to call cleanup(0).
  - Remove the explicit 'return 0' from main(), as cleanup() 
    now handles process termination directly.
  - Ensure the forward declaration for cleanup() matches the 
    updated implementation to prevent C11 type-mismatch warnings.
