Flow declarations can now reference full repository-backed Agent config
without duplicating it inline. The repository response is merged the same
way as `Agent(from_repository=...)`, so values like `role`, `goal`,
`backstory`, `tools`, `planning_config`, deprecated `reasoning`, `memory`,
and other Agent fields can come from the repository. Local YAML fields
still override repository values.
Standalone agent action:
```yaml
do:
call: agent
with:
from_repository: support_specialist
input: "${state.question}"
```
Inline crew agent:
```yaml
do:
call: crew
with:
name: inline_research
agents:
researcher:
from_repository: researcher
tasks:
- description: Research {topic}
expected_output: Findings about {topic}
agent: researcher
```
