Remove tmux-workspaces in favor of tmuxinator-only workflow

- Delete tmux-workspaces.zsh and .tmux-templates directory
- Remove TW_* config settings from dotfiles.conf
- Clean up tmuxinator.zsh (remove import/integration code)
- Update README, INSTALL, and REFERENCE docs
- Fix editor config: .zshrc now uses DEFAULT_EDITOR from dotfiles.conf

+# Tmux workspace management with per-pane commands, environment variables,

 # Features:
-#   - Seamless integration with existing tw-* commands
-#   - Auto-detection: uses tmuxinator if project exists, falls back to templates
 #   - Project scaffolding with sensible defaults
-#   - Import/export between tmuxinator and simple templates
+#   - Multiple built-in templates (dev, ops, web, data, minimal)
+#   - Fuzzy search for projects
 #
 # Requirements:
 #   - tmuxinator (gem install tmuxinator or pacman -S tmuxinator)
