<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Adds a side panel layout for the Command Menu, routes modals into a
local container, updates the top bar and context chips, and standardizes
small button sizes.
> 
> - **Command Menu**:
> - **Side Panel Layout**: Introduces `CommandMenuSidePanelLayout` with
animated width, hosts `CommandMenuRouter`, and provides a modal
container via `ModalContainerContext`.
> - **Top Bar**: Redesign (`CommandMenuTopBar`) with back icon, optional
AI sparkles action, compact height
(`COMMAND_MENU_SEARCH_BAR_HEIGHT=40`), and updated placeholder.
> - **Context Chips**: Adds `CommandMenuLastContextChip` and
`CommandMenuRecordInfo`; extends `CommandMenuContextChip` with `page`
prop; updates `CommandMenuContextChipGroups` to render last chip as
record info when applicable.
> - **Container Simplification**: `CommandMenuContainer` simplified to
just provide contexts and `AgentChatProvider`.
> - **Modal System**:
> - Adds `ModalContainerContext` and updates `Modal` to portal into
provided container; `Modal.Backdrop` supports `isInContainer`.
> - Updates usages (e.g., `UserOrMetadataLoader`, `ActionModal`) to
align with new modal behavior.
> - **Page Integration**:
> - Replaces `PageBody` with `CommandMenuSidePanelLayout` in
`RecordShowPage` and `RecordIndexContainerGater`.
> - Removes global `CommandMenuRouter` from `DefaultLayout` (keeps
keyboard shortcuts).
> - **UI/Styling**:
> - Standardizes several buttons to `size="small"` (e.g., command
actions, open record, options, reply, workflow footer).
> - Adjusts `ShowPageSubContainer` styling when rendered inside command
menu.
>   - Storybook tests updated for new placeholder text.
