Release notes

This version updates structure search coverage and makes several answers clearer. search_structures now covers European patent drawings published from 2025 onward, read by Patent Bear's own optical structure recognition and updated weekly; its description states the new coverage, and hits from those drawings are marked ocr_drawing so the user can confirm them against the drawing. Exact-mode structure searches now return only the identical compound. get_legal_activity adds an opposition status for European patents. get_file_history labels every document with a plain category and adds a one-line summary of the whole file history. When get_family cannot find a worldwide family, it now says how current Patent Bear's family data is instead of returning an error. No tools were added or removed, no arguments changed, and every tool keeps its existing annotations and scopes.

Declared in the saved package. Remote tools may change independently.
