build(format): thread --ignore-path into format scripts

format/format:check ran bare oxfmt --write/--check . without the
--ignore-path .config/fleet/.prettierignore that lint --all already passes,
so `pnpm run format` reformatted cascaded fleet-canonical files (.claude/,
.config/fleet/) it must not touch.
