@repo/logger

@repo/logger provides structured logging for the monorepo. It defines a BaseLogger abstraction and concrete implementations: ConsoleLogger, StructuredLogger (JSON output), and NextJSLogger. Each logger supports info, warn, error, and debug, plus .child() for scoped loggers. Imports use subpaths: @repo/logger/base, @repo/logger/console, @repo/logger/nextjs, and @repo/logger/structured.
