silverwind 20497aaf4f fix: evaluate each ${{ }} part on its own (#1146) ...

Every `${{ }}` part was spliced as raw text into a synthesized `format('...', <raw>)` call and re-parsed, so unbalanced parentheses restructured the whole expression:

```yaml
run: echo ${{ 1) && (2 }}      # panicked with "did not evaluate to a string"
if: ${{ 1 }} ${{ 0) && (0 }}   # silently skipped the step
```

One scanner shaped like GitHub's template reader now splits every value, and each part is evaluated on its own, so nothing builds an expression out of text.

An empty input to `Evaluate` asked `success()` whatever the caller requested, so a post step running under `always()` asked the wrong question.

Same fix as https://github.com/go-gitea/gitea/pull/38754 on the Gitea side.
