release notes

A default-only flag now commits the rest of the line to the default subcommand even when a later word spells a sibling command, and the KDL parser scans strings in chunks so large generated specs load several times faster. The Go modules now require Go 1.26.
Fixed

(parse) Keep the implicit default after a default-only flag (#1418, @lu-zero). With default_subcommand_flags, the lookahead cancelled default routing whenever any later word matched a sibling command or alias, so em -u pkg failed with UnknownFlag -u just because pkg is also a command. Once a default-only flag has been seen, later words are now the default command's arguments: em -u query parses as em install -u query, as do em -X foo query, em -pu query, and --output query search. A sibling name before any default-only flag still selects it (em query, em -p query), and parent-only flags, --help, and bare invocations stay on the parent. Applied consistently to the Rust library, usage-argv, and the Go runtime; fixes #1417.

Changed

(parse) Faster KDL parsing for large specs (#1426, @jdx). Identifier, quoted-string, and raw-string runs are scanned as contiguous slices instead of one Unicode scalar at a time, with escapes, delimiters, newlines, and dedent handling preserved at the boundaries. Parsing the checked-in mise spec drops from 66.9 ms to 16.2 ms in an optimized build, and from roughly 800 ms to 250 ms in a debug build of mise's 321 KB generated spec. Parsed output is unchanged; a regression test covers embedded quotes in multiline raw strings.
(go) The github.com/jdx/usage/go and integrations/cobra modules now declare go 1.26.0 (#1421, @sahidvelji). Projects importing the Go runtime or the Cobra integration need Go 1.26 or newer; expr-lang/expr is now listed as a direct dependency of the runtime module. No behavior changes.
(go) usage generate go emits type X struct{} for a command with no flags, arguments, or subcommands instead of an empty two-line struct body, matching gofumpt output (#1425, @sahidvelji). Regenerating existing code will show this whitespace-only diff.
