* fix(app): record MCP and CLI structural edits as undo steps The automation bridge ran non-atomic tools, render, and eval without an undo entry, so Edit > Undo could not revert layers an MCP client or the CLI created, deleted, or rearranged. Snapshot the page around these edits as the AI chat does, and skip the entry when nothing changed so read-only scripts leave the history alone. * feat(app): activate documents, undo, redo, and change settings over automation Add activate_document, undo, redo, get_settings, and update_settings to the app's automation bridge. Settings cover appearance, snapping, canvas rendering, recovery, and chat preferences, validated with Valibot and applied through their owning stores; credentials, models, MCP connections, storage, and tool access stay out of reach. * feat(mcp): expose document activation, history, and settings tools * feat(cli): manage documents, history, settings, and tools in the running app Turn documents into a command group (list, open, new, save, close, activate), add undo, redo, and settings get/set, and add tool list/describe/call so every MCP tool runs from the shell, against the running app or headlessly on a file. * docs: document app control from the CLI and MCP * fix: never prompt in the app from automation closes and saves close_file opened the app's Save changes dialog, which an agent cannot answer: the call timed out and the dialog stayed open. It now fails on unsaved changes unless the caller passes unsaved "save" or "discard" (CLI --save or --discard). save_file and new_document no longer open a Save dialog for a document that was never saved, report a failed save as an error, and leave the document untouched when the path is refused. * docs: describe non-interactive close and save * fix: address review findings in app automation Keep a document's source when a save to a new path fails, report vector-edit undo and redo no-ops as unapplied, echo only the applied patch from update_settings so writing cannot read settings, reject tool call --write/--output without a file, and stop settings get from following inherited keys. * fix(app): record render undo on the page that receives the layers A render into a parent on another page was snapshotted against the target page, so undo left the new layers in place. Snapshot the page that contains the parent instead, and document that eval edits made after switching pages stay outside the undo step. * feat(app): limit automation undo to its own steps and expose design check settings The undo history is shared with the person in the editor, so an agent's undo could revert the user's last edit. Automation undo and redo now act only on steps made through the bridge, and only while they are newest; otherwise they fail and leave the history alone. Vector edit mode's session history is off limits entirely. Settings automation also covers the design check preferences that landed on master.
