fix(terminals): show script tabs alongside terminals in the drawer

[claude]

Requested via Slack thread

Description

Before: The terminal drawer tab row shows either terminal tabs or script tabs, chosen with a Terminals/Scripts toggle on the right. Reaching a script's Run/Stop control takes an extra click, and script status is not visible while the terminals view is showing.

After: Both groups are always in the row. Terminal tabs (creation order) and the new-terminal button sit in the scrolling region on the left; script tabs (Prepare, Setup, Run, Teardown, configured ones only) are pinned on the right after the divider, with their status icons and Run/Stop actions as before. When no scripts are configured, the divider and script group are not rendered.

How: terminal-drawer-tab-bar.tsx drops the Tabs toggle and the mode/onModeChange props and renders the two role="tablist" groups side by side. terminal-panel.tsx removes the mode state (and the effect and handler that kept it in sync) and derives the active terminal, script, session, and pane-scope store from activeItem.kind, which already comes from the persisted drawer memento. The unreachable "No scripts configured" empty state is removed.

Greptile Summary

This PR removes the terminal/script mode toggle and displays lifecycle-script tabs beside terminal tabs while deriving panel state directly from the persisted active item.

• Keeps terminal tabs and terminal creation in a scrollable left-hand region.
• Pins configured lifecycle scripts and their run/stop controls on the right.
• Simplifies active-session and pane-scope selection in the terminal panel.

Confidence Score: 4/5

The layout overflow should be fixed before merging because narrowing the drawer can make terminal or script controls unreachable.

The new always-visible script group cannot shrink or scroll inside an overflow-clipped row, so configured scripts can consume the available drawer width and hide interactive controls.

Important Files Changed

Filename	Overview
apps/emdash-desktop/src/core/features/terminals/browser/task-terminal/terminal-drawer-tab-bar.tsx	Renders terminal and script tablists concurrently, but the pinned non-scrollable script group can make controls unreachable in a narrow drawer.
apps/emdash-desktop/src/core/features/terminals/contributions/browser/task-terminal/terminal-panel.tsx	Removes mode state and consistently derives the active session and pane-scope provider from the resolved active item.

### Issue 1
apps/emdash-desktop/src/core/features/terminals/browser/task-terminal/terminal-drawer-tab-bar.tsx:145
**Pinned scripts overflow the drawer**

When the drawer is narrow and several lifecycle scripts are configured, this non-shrinking script group consumes the available width inside an overflow-clipped row, collapsing the terminal region and clipping rightmost script controls with no way to scroll to them.
