Typing a partial command (e.g. `bac`) and pressing Enter with no active command ran into an "Unknown command" error. Now the top autocomplete match is highlighted and Enter runs it (`BACKGROUND`), matching standard DWG command-line behavior. The fallback only fires when no command family matches the typed verb, so complete aliases that resolve through a dispatch arm but are absent from the autocomplete registry (`LT`, `ZO`, …) still run as typed. Programmatic dispatch (ribbon, plugins, headless automation) is unaffected. Closes #198 Co-Authored-By: Claude Opus 4.8 <[email protected]>
