fix(generator): Call teardown without begin/end

The omit-begin/end path generated a snake_case call, but the custom
hook is defined as suiteTearDown. Generated C therefore failed strict
C99 compilation.

Constraint: Preserve app-owned Unity lifecycle setup and cleanup
Rejected: Rename suiteTearDown | public docs use this hook name
Confidence: high
Scope-risk: narrow
Directive: Match calls to the emitted teardown hook name
Tested: Targeted regression, strict C99 compile, host run, Ruby syntax
Not-tested: Full scripts suite beyond existing Windows EACCES
