Option to dock the terminal at the bottom of the right panel (IDE-style layout) #17333

Problem

The right panel shows one surface at a time, so the terminal hides the diff, files or browser view. The bottom terminal drawer runs under the chat column, which squeezes the conversation. Most IDEs (VS Code, Cursor, JetBrains) put the terminal under the editor area and leave chat at full height on its own side.

Proposed solution

A setting that docks the terminal in the bottom part of the right panel, with a resizable split between the two:

+-------------+-------------------------+
|             | diff / files / browser  |
|   thread    |                         |
|   chat      +-------------------------+
|             | terminal                |
+-------------+-------------------------+

• The chat column keeps its full height.
• The top area keeps today's tabs (diff, files, browser, PR and so on).
• The terminal toggle (Cmd+J) opens and closes the bottom section rather than the drawer under chat.
• The split height persists like the current drawer height.
• The setting is off by default, so nothing changes for anyone who doesn't opt in.

#9593 proposes keeping the terminal beside the diff in an extra column. This idea stacks it below instead, which keeps the familiar IDE layout and fits narrower windows. #6930 asks for general split-pane management; this is a much smaller, fixed layout.
