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

5 

6This module contains the logic for removing a key-value pair from the active 

7configuration store. It provides a structured, machine-readable response to 

8confirm the deletion or report an error, such as if the key does not exist. 

9 

10Output Contract: 

11 * Success: `{"status": "deleted", "key": str}` 

12 * Verbose: Adds `{"python": str, "platform": str}` to the payload. 

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

14 

15Exit Codes: 

16 * `0`: Success. 

17 * `1`: An unexpected error occurred while accessing the configuration. 

18 * `2`: The specified key was not found in the configuration.

55 This function orchestrates the `unset` operation. It manually parses global 

56 flags, resolves the configuration service, attempts to remove the specified 

57 key, and then uses the `new_run_command` helper to emit a structured 

58 payload confirming the action.

61 ctx (typer.Context): The Typer context for the CLI. 

62 key (str): The configuration key to remove. 

63 quiet (bool): If True, suppresses all output except for errors. 

64 verbose (bool): If True, includes Python/platform details in the output. 

65 fmt (str): The output format, "json" or "yaml". 

66 pretty (bool): If True, pretty-prints the output. 

67 debug (bool): If True, enables debug diagnostics.
