4"""Implements the `config reload` subcommand for the Bijux CLI. 

5 

6This module contains the logic for manually reloading the application's 

7configuration from its source file on disk. It discards any in-memory 

8settings and replaces them with the content of the configuration file, 

9emitting a structured confirmation upon success. 

10 

11Output Contract: 

12 * Success: `{"status": "reloaded"}` 

13 * Error: `{"error": str, "code": int}` 

14 

15Exit Codes: 

16 * `0`: Success. 

17 * `2`: The configuration file could not be read or parsed.
