fix: resolve new tab creation failure and shortcut passthrough

- Fix pty.spawn cwd tilde expansion: ptyManager now passes resolvedCwd (expanding ~ and verifying directory existence) so child processes do not exit immediately on launch
- Add pointer-events: none to SVGs inside buttons and tabs to prevent Electron window-dragging interception
- Extend xterm attachCustomKeyEventHandler to allow Ctrl+Shift+T, Ctrl+Shift+W, etc. through while terminal is focused
- Wrap remote SSH and serial spawns with fallback to local bash to prevent tab death loops on connection failures
