Noteable additions: - `redefines-builtin-id` forbid variable names that shadow go builtins - `empty-lines` remove unnecessary empty lines that `gofumpt` does not remove for some reason - `superfluous-else` eliminate more superfluous `else` branches Rules are also sorted alphabetically and I cleaned up various parts of `.golangci.yml`.
