## Summary
- Register Wikipedia component + tool alias
`wikipedia`/`wikipedia_search`
- Use `generator=search` to get title/summary/url in one request (was
N+1)
- Node params `top_n`/`language` with validation
- Return `formalized_content` for downstream
- tests pass

## Summary
- align the Go Google Scholar component with the Python-side config
pattern
- merge node-level params with runtime inputs so canvas defaults are
preserved and per-run inputs can override them
- add tests covering node param fallback and runtime override behavior
## Verification
- `bash build.sh --test ./internal/agent/component/... -run
TestGoogleScholar`

### Summary
- TavilySearch now stores api_key from component params and injects it
into tool calls when runtime inputs omit it.
- TavilyExtract and BGPT now follow the same stored api_key behavior.
- Canvas decoding now recovers api_key from graph.nodes[].data.form when
components[].obj.params.api_key is empty, matching frontend payload
behavior without changing frontend data.
- Added regression tests for graph form key recovery and stored key
injection / caller key precedence.
Tests: build.sh --test ./internal/agent/component ./internal/service —
all pass.
