Tab completion for slash commands crashes with React rendering error

When pressing Tab to autocomplete a slash command (e.g., /update-docs), Claude Code crashes with a React internal error.

Steps to reproduce:

1. Open Claude Code in any project
2. Start typing a slash command, e.g., /update
3. Press Tab to trigger autocomplete
4. UI crashes with React error

Expected behavior:
Tab completion should show available slash commands matching the typed prefix.

Actual behavior:
Application crashes with a React/rendering error in the autocomplete UI component.

Workaround:
Typing the full command and pressing Enter works correctly.

Error output:
N1(4194308,4,E,K)},useInsertionEffect:function(E,K){N1(4,2,E,K)},useMemo:function(E,K){var P=fR();K=K===void 0?null:K;var u=E();if(YQ){RT(!0);try{E()}finally{RT(!1)}}return P.memoizedState=[u,K],u}
