Summary

The bottom panel can now sit in a column on the right of the terminal, for wide screens where the terminal needs the height more than the width.

• The tab row's context menu (bottomPanelMenu) gets "Move panel to right side" / "Move panel to bottom", after a separator under Hide/Show panel.
• On the right, the main area is a horizontal split: the terminal with its command bar on the left, the panel on the right, full height. The column is rightPanelWidth wide: 460 DIPs by default, at least 410 (what the Processes details' fields-and-environment split needs, 200 + 200 + the divider, so the inner dividers keep working), and the terminal keeps at least 320. It is dragged, a double click resets it, and it is saved through saveLayout/restoreLayout.
• The column's width stays fixed from the right edge when the window is resized. ui.Split sizes its first pane, so withRightColumn lays the split out in the opposite direction (its first pane is then the end one, which is the column) and sets each pane back to the window's own direction. Dragging, the arrow keys and SplitReset all work in column DIPs with no per-frame arithmetic. The other option, a left-to-right split sized to width - rightWidth from last frame's bounds, lags one frame on resize and makes the reset value depend on the window.
• withRightColumn(c, main, top, bottom) / rightColumn(c, top, bottom) in internal/app/rightcolumn.go are written for feat(app): put the server monitor on the right of the terminal #152: the monitor goes in as top, the panel as bottom. When both are there they split with SplitVerticalPercent on a.rightMonitorPct (default 45, rightMonitorLimits). Only the panel goes in for now. The rightMonitorPercent settings key is left to feat(app): put the server monitor on the right of the terminal #152.
• Hidden on the right: the column goes away, and a thin strip at the terminal's right edge holds the "Show panel" button (chevron left; new chevron-left.svg from Lucide) and the panel's context menu. The hide button in the tab row is a chevron right. The shortcut, and anything that calls openBottomTab (such as the monitor's process list), show it again.
• Narrow column:
  • The panel's tabs are in a ScrollHorizontal with hidden scrollbars, tracked by a ui.ScrollState. Its HandleInput hook (tabsWheel) turns a plain vertical wheel, or a vertical touchpad swipe, over the tab row into sideways scrolling while the tabs do not fit (down goes toward the last tab). When they fit, or the scroll is sideways or has Ctrl, the event goes on as before.
  • The Files table already scrolls its columns sideways.
  • The Processes and Network filter fields can shrink to 120 DIPs, and the process count no longer shrinks to "7 pr…".
  • At the bottom in a normal window nothing changes: go run ./tools/screenshots produced identical README images.
• A panel row ignores the side. Full screen is unchanged.
• Settings: bottomPanelSide ("" / "right") and rightPanelWidth are added to config.Settings and localSettings. Docs: features.md (Window layout; Layout and split dividers) and configuration.md (the table and the local-keys list), English and Simplified Chinese.

Testing

• New tests in internal/app/rightcolumn_test.go:
  • TestPanelOnRight: move right and back with the menu; side saved and read back; the terminal gets more rows and fewer columns.
  • TestRightPanelWidth: drag the divider; width saved and read back; terminal and column limits; double-click reset; the width stays fixed when the window grows.
  • TestPanelHiddenOnRight: hide and show with the button and the shortcut; the monitor's process click shows it; the strip's menu moves it back to the bottom, still collapsed; a panel row is unaffected; full screen.
  • TestPanelOnRightTabDividers: the Processes list/fields and Network list dividers drag, save, restore and reset at 460 and 410 DIPs.
  • TestPanelTabsWheel: at 410 DIPs the Commands tab is cut off. A vertical wheel over the tab row brings all of it into view without moving the buttons, the wheel back up returns to Files, and a wheel over the terminal leaves the tabs alone. The test fails with the hook removed.
• gofmt -l . (go.mod toolchain) prints nothing. go build ./..., go vet ./..., GOOS=windows go vet ., GOOS=darwin go vet . and go tool mygo vet pass.
• go test -race ./... passes except TestArchiveTreeMenu, which also fails on main in this sandbox (it tars the real /tmp).
• Screenshots were looked at but not committed: panel on the right on Files and on Processes, and hidden on the right, in English and Simplified Chinese; Processes details and Network at 460 and 410 DIPs; the tab row before and after the wheel.
• Not tested: a real window on macOS, Windows or Linux; real mouse wheels and touchpads; a right-to-left window direction (the app has no RTL language, but the code reads c.Direction()).
