Give the coordinator working crew management tools

- Resolve the crew and workspaces fresh inside each tool run, so a bot or
  workspace created earlier in the same reply is usable: create_bot,
  assign_computer, add_bot_to_workspace, delegate_task and
  set_bot_workspace_instructions.
- Add coordinator-only update_bot, find_bot, find_workspace, delete_bot,
  delete_workspace and remove_bot_from_workspace tools.
- Push server:workspace-removed when a workspace is deleted, and
  workspace_ids on server:bot-updated so a workspace's crew drops a bot
  that was taken out of it.
