Add machine-readable help catalog: mlr help --json (#2098) (#2099) 
Emit Miller's existing help catalog (verbs, functions, flags, keywords)
as structured JSON so AI agents and tooling can model Miller's surface
without scraping prose. The --json token may appear anywhere on a
`mlr help ...` command line; plain text help is unchanged.

  mlr help --json                  # full catalog
  mlr help verb cat --json         # one or more verbs
  mlr help function splitax --json # one or more functions
  mlr help flag --ifs --json       # one or more flags
  mlr help keyword ENV --json      # one or more keywords

Functions and flags serialize fully (name/class/arity/help/examples;
section/name/alt_names/arg/help). Verbs carry a summary, ignores_input,
and captured raw usage_text as a Tier-1 fallback, since per-verb options
are prose-only today (each verb hand-writes its UsageFunc). Structured
verb options are a planned follow-on (see #2098).

This is a serialization layer over the existing registries -- no
refactor of the text-help path.
