Vinicius Brasil c1a70d84d0 Add expressions to FlowDefinition actions ...

Let definitions compute values without Python. A new `call: expression`
action evaluates a Common Expression Language (CEL) expression, and tool
`with:` blocks now render `${...}` CEL templates.

Example 1:

```yaml
decide:
  do:
    call: expression
    expr: "state.score >= 80 ? 'qualified' : 'nurture'"
  router: true
  emit: [qualified, nurture]
```

Example 2:

```yaml
search:
  do:
    call: tool
    ref: my.pkg:SearchTool
    with:
      search_query: "${outputs.build_query.query + ' news'}"
      max_results: "${state.limit}"
```
