* refactor: update semantic search parameter from `last_user_message` to `search_query` across documentation and SDKs
- Changed references in documentation and code to use `search_query` instead of `last_user_message` for fetching semantically relevant observations and conclusions.
- Updated related function signatures and descriptions in Python and TypeScript SDKs to reflect this change.
- Adjusted tests to ensure compatibility with the new parameter naming.
* chore: openapi v3 formatted how we like it
* fix: reorder docs, update examples in README, update skills
* fix: message type option in sdk reference
* chore: update remaining getcontext and representation language
