Mark read-only MCP connector tools as read-only (Claude)

In Claude, every Hudu MCP connector tool shows under "Other tools" instead of being classified as a read or write tool. Our organization does not allow "Always allow" for write tools, and "Other tools" are treated the same way, so someone has to approve every call, including simple lookups.

• Set MCP tool annotations on each tool: readOnlyHint true on tools that only read (index, show, search and similar).

• Set readOnlyHint false, with destructiveHint where appropriate, on tools that create, edit, archive or delete.
