Contract
- alt falls back to alternative branches on complete slices when a branch encounters insufficient data
- alt aborts with ErrMode::Incomplete on Partial streams on insufficient data without evaluating subsequent branches
- complete_err transforms ErrMode::Incomplete into ErrMode::Backtrack to re-enable alt fallback across streaming Partial inputs
- alpha0 on Partial streams yields Incomplete at EOF unless explicit stream completion is signaled via StreamIsPartial::complete
