Subject: [PATCH] feat: add AppAction enum and Doom Emacs keybinding
 configuration

18-variant AppAction enum + build_normal_keymap() with hjkl, gg/G, gt/gT,
1-6 tabs, C-d/C-u, SPC leader tree (buffer/help/quit/notifications).

Ultraworked with [Sisyphus](https://github.com/code-yeongyu/claude-agent)
