* refactor: extract shared code for linting if-else chains The rules "early-return", "indent-error-flow" and "superfluous-else" have a similar structure. This moves the common logic for classifying if-else chains to a common package. A few side benefits: - "early-return" now handles os.Exit/log.Panicf/etc - "superfluous-else" now handles (builtin) panic - "superfluous-else" and "indent-error-flow" now handle if/else chains with 2+ "if" branches * internal/ifelse: style fixes, renames, spelling
