* fix: update openclaw tests to use before_prompt_build hook and split doc-examples CI per language
- Update hooks.integration.test.ts: rename describe block and all
triggerHook calls from 'before_agent_start' to 'before_prompt_build'
to match the hook registered in index.ts (changed in PR #480)
- Fix 'includes the user message' test: prependContext contains memories
(bullet list), not the raw user query; update assertion accordingly
- Split test-doc-examples CI job into a matrix over [python, node, cli, go]
so each language runs in parallel; language-specific setup steps
(Rust/CLI build, Node.js, Python client, TypeScript client) are
conditional on matrix.language to avoid unnecessary work
* fix: spy on HindsightClient prototype to intercept all per-bank client instances
getClientForContext creates new HindsightClient instances per bank when
dynamicBankId is true, so vi.spyOn(c, 'recall') on the default client
never captured calls. Spy on HindsightClient.prototype instead so all
dynamically created bank clients are intercepted.
