chore(config): Refactor Emacs config for cross-platform compatibility

Add Android/Termux support with `*is-android*` constant and
conditional GUI/terminal initialization. Remove maximized frame
defaults and custom.el. Replace corfu with corfu-terminal in
TTY. Add god-mode to terminal config with line number sync. Update
org agenda to use org-ql blocks with super-agenda grouping. Switch
solarized-theme to fork. Clean up redundant functions and unify
keyboard bindings across environments.
