Config-action slash commands for Copilot agent-host chat inputs (#326807) * Config-action slash commands for Copilot agent-host chat inputs Add permission/mode slash commands (e.g. /yolo, /autopilot on|off, /autopilot <objective>, /plan <prompt>) for Copilot agent-host chat sessions in both the editor window and the Agents window. Selecting one toggles the corresponding session-config axis (autoApprove or mode) and updates the permission/mode pickers, instead of sending a chat turn. Items are produced server-side by the Copilot completion provider and carry an `action` bag on the completion attachment `_meta`; a shared client accept-handler runs the elevated-permission confirmation for elevated autoApprove values and applies the change via a per-window seam (editor: AHP dispatch/provisional; Agents: provider.setSessionConfigValue). Toggle items insert nothing (insertText ''); prompt items keep `/cmd ` plus an argument hint. On send, the leading token is stripped and the mode re-applied so it is not dispatched to the runtime. Elevated auto-approve items are omitted when enterprise policy disables global auto-approval. The old hardcoded permission commands are unscoped from agent-host Copilot sessions so the completion pipeline solely owns them. Fixes #325890 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Scope Agents-window config-action completions to the input's session The Agents-window `AgentHostInputCompletionHandler` resolved the window-global `ISessionsService.activeSession`, so accepting a config completion in a non-active composer could apply the permission/mode change to a different (same-type) session. Create the handler via the input's scoped instantiation service and resolve the session from the input-scoped `ISessionContext` instead, matching how the sibling `SlashCommandHandler` and the editor-window handler bind to their own input's session.
