[idea] Option to place the sidebar on the right

[gustavocaiano]

idea / problem

The sidebar (workspace + agent panel) is fixed on the left side of the window. There is no config option to move it. The only positional chrome option today is tab_bar_position = "top" | "bottom".

requested change

A config option to place the sidebar on the right, e.g.:

[ui]
sidebar_position = "left"   # or "right"

Following the same pattern as the existing tab_bar_position.

why you want this

• Left-handed users who keep their right hand on the mouse reach the right edge more naturally.
• RTL readers (Arabic, Hebrew) for whom a right-anchored panel matches reading direction.
• Muscle memory from IDEs (VS Code, JetBrains) where the activity bar / project panel can be docked on the right.

tab_bar_position already proves herdr supports configurable chrome placement; mirroring that for the sidebar feels consistent and low-scope.

This is a pretty big one for me. I like to have my code lined up and consistent. If I show/hide a sidebar, I'd prefer that happen on the right side of the screen.

+1, I'd really like this too. Worth noting an implementation already exists — PR #2287 (feat(ui): support right-aligned desktop sidebar) added a [ui] sidebar_position. Would be great to see it revived.
