- help.fish: expand SYNOPSIS/DESCRIPTION to document -w/--html, -m/--man,
-h/--help flags; note flags are only intercepted when 'config' is argv[1]
- config-help.fish: add # NOTES section explaining help config as the
preferred invocation; update --help banner to show both names; update
--help USAGE/EXAMPLES output to use `help config` syntax throughout
- docs/fish-config.md: update §5.14 synopsis/examples and "Viewing" sections
to use `help config` as primary form; inline note for direct config-help use
- README.md: update docs table to show `help config --html` / `--man`
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.
