fix(container): unbind zsh Alt+W and Alt+Q keybinds

Alt+W (copy-region-as-kill) and Alt+Q (push-line) are unused emacs
line-editor operations that occupy useful Alt key slots. Removed
alongside the existing Ctrl key hardening.

-- **Shell terminal keybinds hardened** — disabled `Ctrl+Z` (suspend, which closes Docker-attached panes), `Ctrl+S/Q` (flow control freeze), and `Ctrl+W` (conflicts with Windows Terminal close-tab). Rebound `Ctrl+\` (SIGQUIT) to `Ctrl+]` and `Ctrl+D` (EOF) to `Ctrl+^` as emergency-only alternatives.
