-================================================================================
-Retri Configuration File (config.yaml) Reference
-================================================================================
-
-This file is written in YAML format. The variables allowed in each section are
-strictly defined.
-
---------------------------------------------------------------------------------
-Variable Precedence & Aggregation Rules
---------------------------------------------------------------------------------
-
-1. Single Variable Priority (<)
-   Evaluation Order: defaults < groups < device_types < hosts < env vars < CLI
-   (Values on the right override values on the left.)
-
-   Environment variables:
-     - RETRI_SSH_PASSWORD: Overrides password from config (but not CLI -p)
-     - RETRI_SSH_SECRET:   Overrides secret from config (but not CLI -s)
-
-2. Command Aggregation (+)
-   Execution Order:  defaults + groups + device_types + hosts
-   (Commands are concatenated in this order and all are executed.)
-
---------------------------------------------------------------------------------
-Section Definitions & Available Variables
---------------------------------------------------------------------------------
-
-[defaults] Section
-  Sets global default values for the application.
-
-  Available Variables:
-    user, password, secret        : SSH/Sudo credentials (default fallback).
-    command, commands, command_file
-                                  : Commands to execute.
-    log_dir                       : Directory path for saving logs.
-    suffix                        : Suffix string appended to log filenames.
-    device_type                   : Default device type (e.g., "linux").
-    parallel                      : Parallel execution count or "auto".
-    timestamp                     : Enable/disable timestamp in logs (true/false). [defaults only]
-    filename_format               : Format string for log filenames. [defaults only]
-    timestamp_format              : Date format string for filenames. [defaults only]
-
-[device_types] Section
-  Defines settings specific to device types. Keys are arbitrary identifiers
-  (e.g., "cisco_ios", "linux").
-
-  Special Behavior for 'linux':
-    If device_type is set to "linux", commands are executed via direct SSH execution
-    (non-interactive, no PTY) to ensure clean output without terminal control codes.
-    All other types default to interactive PTY sessions.
-
-  Available Variables:
-    setup_commands                : Commands executed immediately after login. [device_types only]
-    prompt_regex                  : Regex to detect command prompts. [device_types only]
-    exit_command                  : Command to exit the session (default: "exit").
-                                    Use "quit" for Huawei devices. [device_types only]
-    user, password, secret        : Credentials common to this device type.
-    command, commands, command_file
-                                  : Commands common to this device type.
-    log_dir                       : Log storage directory for this type.
-
-[groups] Section
-  Groups multiple hosts together for shared configuration.
-
-  Available Variables:

-    hosts                         : List of hostnames belonging to the group.
-                                    (e.g., ["host1", "host2"])
-    user, password, secret        : Credentials common to the group.
-    command, commands, command_file
-                                  : Commands common to the group.

-    suffix                        : Suffix for log files in this group.
-    device_type                   : Device type applied to this group.
-
-[hosts] Section

-                                    (e.g., ["group1"])
-    user, password, secret        : Host-specific credentials.
-    command, commands, command_file
-                                  : Host-specific commands.
