refactor: standardize file-level comments, drop unused pkgs, and theme lazygit with base16

- Move inline comments to top of file across all modules for consistent
style
- Add descriptive comments to files missing them (aggregators,
assertions, scripts, flake)
- Remove unused `pkgs` parameter from i3/keybindings.nix and
zathura/default.nix
- Drop explicit `package = pkgs.zathura` (home-manager provides the
default)
- Delete stale meli-sync.sh (migrated to neomutt)
- Remove extraneous blank lines for consistent formatting
- Theme lazygit with config.scheme base16 colors instead of hardcoded
names
