models occasionally call `pullfrog_git({command:"status", args:["status"]})`,
which shells out to `git status status`. git silently treats args[0] as a
pathspec — when no file/dir matches, status prints "nothing to commit,
working tree clean" even on a dirty tree. observed in production
(Skn0tt/beckerbuch run 26519563044): the agent looped trying to reconcile
that against a real diff, burned ~$3 / ~6min of opus, and only escaped when
it switched to `args: ["--porcelain"]`. generalises to every subcommand
(`diff diff`, `log log`, ...).
guard `args[0]?.toLowerCase() === command.toLowerCase()` with a directed
throw pointing the model at the disambiguated `args: ["--", "<name>"]`
escape hatch for the rare legitimate pathspec case (`--` works under every
subcommand, unlike a bare positional which can be parsed as a ref by
log/diff/checkout/restore/reset).
description also leads with the no-args case and explicitly forbids
repeating the subcommand in args. schema already had args.optional().
