fix: search_tools now includes direct tools (snapshot_project etc.)

- searchTools() previously only searched routed tool categories, so
  direct tools like snapshot_project, save_project, create_project
  returned 0 results when Claude called search_tools('snapshot')
- Direct tools are now searched first, with a hint that they must be
  called directly (not via execute_tool)

Also includes routing.py zone-inset fix for rounded board corners
(already staged from previous session)
