The Export dialog's GIF choice runs through SlideApp::export_as (desktop and web download),
.gif is a writable output extension for convert/run, and the CLI help pages describe GIF output
and --export-params. A file.export `slides` range string ("1-3,5") works for GIF as for PDF.

file.export's slide range and transition.sound's keys parse as parameters, and the subcommands
main added since #303 have their own help page.

A --cmd without a value now asks for COMMAND[=PARAMS]. The params field
says how describe reads it, table.split's row and col are optional as
the command reads them, and the MCP instructions name only shape
commands for `ids`.

`deckcraft-cli help` and each subcommand's `--help` say what it does,
with a working example; `--help` never runs the subcommand. `describe`
spells out a command's parameters and what it acts on, `commands` lists
one command per line, and the MCP instructions say what format.* acts on.
