feat(wezterm): unify navigation with XMonad keybindings

Add sequential pane navigation and rotation to match XMonad's window
management pattern. This creates consistent muscle memory across both
the window manager and terminal multiplexer.

Changes:
- Add Alt+PageUp/PageDown for sequential pane focus (mirrors XMonad's window cycling)
- Add Alt+Ctrl+PageUp/PageDown for pane rotation (mirrors XMonad's rotAll)
- Change Leader+Tab to Leader+t for new tab (free up 't' was for zoom, now 'm')
- Change zoom from Leader+t to Leader+m (matches XMonad's maximize mnemonic)

Keybinding philosophy:
- Base keys (Alt+PageUp/Down) = navigation/viewing
- Ctrl modifier = structural control (resize/rotate)
- Consistent with XMonad: Mod+PageUp/Down (focus), Mod+Ctrl+PageUp/Down (rotate)
