Assistants sign in, and three tools reach the whole API

REST API

New: PATCH/drive-documents/{drive_document} accepts "mode": "append", which adds the new content after the existing text instead of replacing it.
Fixed: DELETE/projects/{project} now says correctly that a soft delete keeps the project's notes, Drive items and tags; only force=true removes them.

New: claude.ai, ChatGPT and other AI assistants connect by signing in to plnnrly, so no token is needed. See Pick your client.
New: An assistant can delete once an administrator switches on Allow destructive actions, and only after you confirm the delete.
New: An assistant asks for your confirmation before it replaces a whole Drive document.
New: The MCP & API page has its own permissions, View MCP & API and Manage MCP & API. Roles that could open or change the page before keep that right.
Changed: Three general tools, search_api, api_read and api_write, replace the tool per feature. Together they reach every REST API operation except file uploads. See Tools.
Changed: New personal MCP tokens can no longer be created. Existing ones keep working.
Changed: MCP only works while the REST API is on. Organisations that had MCP on and the REST API off got the REST API switched on, so their assistants keep working.
Changed: New organisations start with MCP off. Existing organisations keep their setting.
