feat(help): integrate config-help into fish's help command

Rename config_help → config-help and add a help wrapper that
intercepts 'help config [section]', forwarding sub-topics to
config-help. Update README and docs to use 'help config' as the
preferred interface so offline docs feel like a natural extension
of fish's built-in help system.

# Copyright (C) 2026 Rootiest
# SPDX-License-Identifier: AGPL-3.0-or-later
# SYNOPSIS
# help [topic] [sub-topic...]
#
# DESCRIPTION
# Wraps the built-in Fish help command. Intercepts the specific topic "config"
# and forwards any subsequent sub-topics/arguments straight to the custom
# 'config-help' utility. For all other topics, it forwards the arguments
# intact to the original, built-in system help utility.
#
# ARGUMENTS
# topic Optional string representing the primary help subject (e.g., "config").
# sub-topic Optional additional arguments passed exclusively to 'config-help'.
#
# RETURNS
# 0 Successful execution of config-help or the original system help command.
# >0 Failure status returned by the underlying help utilities.
#
# NOTES
# To prevent infinite recursion, the wrapper must backup the native system function
# on the first run. Because Fish lazy-loads functions dynamically, we explicitly
# source the system file and clone it to '__original_help' if it doesn't already exist.
#
# EXAMPLE
# help config keys
# # Executes: config-help keys
#
# help string
# # Forwards to the standard fish documentation for 'string'
# --- Initialization & Backup ---
