v0.1.4

Reworked Debug, Info, Warn, and Error methods to accept variadic arguments
instead of a single message + key-value pairs. Now log methods can be called
with any number of values, which are joined with spaces and logged as a single
line.

Example:
barelog.Info("Loading", "file", filename, "completed")

This simplifies logging and avoids the key=value formatting logic. It also
improves flexibility when logging dynamic or composite messages.
