…etBrains#1370) * feat(web): run tab layout actions from the palette and chords Tab menu availability moves into one pure tabActions source that the context menu and a new Active tab palette group both read. New chords: Mod+Alt+W closes the active tab (Mod+W stays desktop-owned and display-only), Mod+\ splits right, Ctrl+Alt+Left/Right (Ctrl+Cmd on macOS) moves the tab to the adjacent group. Shift+F10 / Menu opens tab and rail menus. Chords can be platform-specific or display-only, and no Alt chord matches under AltGraph. * feat(web): navigate the sidebar trees with the keyboard Files, Changes, Specs, Chats and Projects share one DOM-driven tree model: one Tab stop per tree on the current row, arrows, Home/End, type-ahead, Enter and Mod+Enter, Shift+F10 for every row menu, Delete through the existing confirmations and F2 for project and workspace rename. The current row carries data-focus-default, so F6 and the focus chords land on it. * fix(web): land a focus chord on the loaded tree, not the toolbar above its skeleton * fix(web): land on the tree's current row and keep tree markup valid A remembered treeitem or tab that stopped being its roving container's tab stop no longer wins the landing. Pointer-only row controls inside a tree are aria-hidden. The AltGraph guard applies only off Apple, where Firefox reports Option as AltGraph. * fix(web): let Mod+Alt+W dismiss an open layer before closing the tab

Problem
ThinkRail's desktop Monaco source editor provided standard Monaco navigation only. Vim-oriented users lacked familiar motions, Visual selection, marks, jump history, and search while reviewing source files.
The source editor is intentionally read-only, so the feature must not turn source files into editable buffers.
Approach
Add a renderer-local, opt-in Vim controller around the existing desktop Monaco editor. Keep Vim disabled by default, preserve standard Monaco behavior while disabled, and expose only a narrow public hook so the web shell can toggle the focused editor from the command palette without coupling the renderer to shell internals.
The supported command set follows the high-value navigation subset documented by Vim and available in compact Linux Vim builds such as Debian
vim.tiny. Mutation operators, registers, clipboard, Ex commands, undo/redo, macros, terminal behavior, and mobile Pierre rendering remain out of scope because the source surface is read-only.Changes

Before: desktop Monaco source editor on the base branch, Vim control absent.
After: same scenario and viewport with the Vim control enabled.
