feat(shortcuts): add configurable shortcut to show Files sidebar

[roberto-fernandino]

Summary

• Adds a new keyboard shortcut ⌘⇧G (Cmd+Shift+G, configurable) that switches the sidebar to the Files/explorer view
• Pairs naturally with ⌘G (source control) so you can toggle between them without touching the mouse
• Exposed as "Show Files sidebar" in the command palette
• Fully customizable in Settings → Shortcuts like all other shortcuts

Motivation

After pressing ⌘G to open Source Control, there was no keyboard shortcut to switch back to the Files sidebar — users were forced to click with the mouse.

How it works

Uses cycleSidebarView("explorer") — the same pattern pane.source uses for source-control:

• If sidebar is collapsed → expands it and shows Files
• If sidebar already shows Files → collapses it
• If sidebar shows Source Control → switches to Files

Three files changed:

• src/modules/shortcuts/shortcuts.ts — adds "sidebar.files" shortcut id + entry
• src/modules/command-palette/commands.ts — adds context field + command palette item
• src/app/App.tsx — wires up the handler

Test plan

• Open source control with ⌘G, then press ⌘⇧G — should switch back to Files
• Press ⌘⇧G when sidebar is collapsed — should expand and show Files
• Open command palette and search "Show Files" — should appear and work
• Go to Settings → Shortcuts and verify "Show Files sidebar" is listed and rebindable

📝 Walkthrough

Walkthrough

The PR bumps the pnpm packageManager version and updates space-scoped tab selection, AI and explorer shortcut wiring, and terminal-tab command-palette items.

Changes

Navigation and command palette controls

Layer / File(s)	Summary
Space-scoped tab selection src/modules/tabs/lib/useTabs.ts, src/modules/tabs/lib/pickTabBySpaceIndex.test.ts, src/app/App.tsx	selectByIndex now accepts an optional spaceId, the tab helper filters by space before indexing, and the app shortcut passes the active space into tab selection; tests cover per-space indexing.
AI and explorer controls src/modules/shortcuts/shortcuts.ts, src/modules/command-palette/commands.ts, src/modules/ai/components/AiStatusBarControls.tsx, src/app/App.tsx	Shortcut IDs and command-palette context add ai.toggleMini and sidebar.files; App wires the mini chat toggle, explorer cycling, and the new command-palette explorer action, and the AI status-bar button changes its title and disabled state.
Terminal tab commands src/modules/command-palette/commands.ts, src/app/App.tsx	The command palette adds a Terminals group, accepts terminal tabs and switchTab, and generates tab-switching items that activate by id.

Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

Inline comments:
In `@src/app/App.tsx`:
- Around line 643-647: The `shortcutHandlers` memo in `App.tsx` is missing
`activeSpaceId`, so the `"tab.selectByIndex"` handler can keep using a stale
space after switching spaces. Update the dependency list for the
`shortcutHandlers` memo (and any related memoized shortcut setup around the same
block) to include `activeSpaceId`, so `selectByIndex` always resolves against
the current space. Verify the Cmd+1..9 path uses the latest `activeSpaceId`
rather than a previously captured value.

In `@src/modules/ai/components/AiStatusBarControls.tsx`:
- Around line 173-174: The mini-chat status bar control in
AiStatusBarControls.tsx is only opening the window because its onClick handler
always points to openMini, even though the title now reflects an open/close
toggle. Update the click behavior in the status bar button so it actually
toggles the mini chat state by calling the appropriate open/close handler based
on miniOpen, and keep the title in sync with that same state logic.
