Adds a new internal MCP server (`conversation_side_panel`) that lets the activation agent open/close frames in the conversation side panel instead of rendering them inline. - New server with two tools: `open_frame` (open a specific file frame by ID) and `set_files_side_panel` (show/hide the files panel) - Registers a `side_panel_control` progress-notification output schema and filters it from the public v1 API (UI-only signal) - Wires the server into `INTERNAL_MCP_SERVERS`, `getInternalMCPServer`, and the activation skill MCP server list - Updates the activation skill system prompt: frames are now delivered via `open_frame` rather than rendered inline - Adds BM25 search test cases for the new tools Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Same pattern as tool_approval_bubble_up and other notification types. Avoids a type cast in backward_compatibility.ts. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
side_panel_control is now in the SDK NotificationContentSchema union, so no cast or filtering is required here. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Honor the activation agent's explicit files panel preference so generated-file auto-open behavior cannot override it. Co-authored-by: Cursor <cursoragent@cursor.com>

Honor completed panel-control actions after a conversation reload so generated files cannot reopen the files panel against the agent's instruction. Co-authored-by: Cursor <cursoragent@cursor.com>
