Five issues + keyboard shortcuts across booterm and the workspace shell.
Auto-switch on create (mobile): addSplitPane now returns the new pane id;
Session.tsx wraps it with addPaneAndSwitch which pushes ?pane=<newId> on
mobile so the URL-sync effect doesn't fight the just-set activePaneIdx.
NewPaneMenu uses the wrapper; desktop Split dropdown is unaffected.
Tab-away reconnect: TerminalPane has a connect()/manualReconnect() state
machine. ws.onclose backs off 500ms/1s/2s × 3 attempts, then surfaces a
[Disconnected] banner with a Reconnect button. visibilitychange listener
calls manualReconnect when the tab returns and the WS isn't OPEN. tmux
session persists server-side so scrollback is intact on resume.
Copy/paste: attachCustomKeyEventHandler binds Cmd/Ctrl-C (copy if
selection, else send ^C), Cmd/Ctrl-Shift-C (always swallow — copy if any,
no-op otherwise — never sends ^C), Cmd/Ctrl-V and Cmd/Ctrl-Shift-V
(navigator.clipboard.readText → ws.send). No custom right-click menu —
browser's native menu is preserved.
Scroll: removed `set -g mouse on` from tmux.conf so xterm.js sees wheel
and touch events natively. scrollback: 10_000, fastScrollModifier: 'shift',
altClickMovesCursor: false. Container has touch-action: pan-y for mobile.
Right-edge gap: inline <style> overrides xterm's defaults to width:100%
height:100% and hides the scrollbar chrome. Host container is
flex-1 min-w-0 self-stretch w-full. Three refit triggers: ResizeObserver
(rAF-wrapped), document.fonts.ready, and useEffect on the new active prop.
Background color matched between outer div, inner div, and xterm theme.
Keyboard shortcuts in Session.tsx (window-level keydown):
Cmd/Ctrl+` focus active terminal, else jump to last
Cmd/Ctrl+Shift+T new terminal pane
Cmd/Ctrl+Shift+C new chat pane (defers to xterm copy if focused)
Cmd/Ctrl+W close active pane
Cmd/Ctrl+Tab/Shift+Tab cycle next / prev pane
Cmd/Ctrl+1..9 jump to pane N
terminalsRegistry gains a focus() callback per registration so Cmd+`
can call term.focus() on the active terminal.

Switched the booterm runtime + proddeps stages from node:20-alpine (musl)
to node:20-bookworm-slim (glibc) so host-installed glibc binaries (Claude
Code, opencode, nvm node) run inside the container when invoked from the
terminal pane. node-pty's native .node has to be compiled in the same
libc env as the runtime, so both stages flip together; the TypeScript-only
builder stage stays on alpine.
su-exec is alpine-only; Debian replacement is gosu — swapped in both the
runtime apt install and the tmux default-command. uid/gid 1000 collision
with the bookworm `node` user handled via userdel/groupdel before
groupadd/useradd.
