feat: add message replacement for log records

Add Logger.AddReplacer to mask or normalize message text before records reach writers.
Document replacement behavior in README and package GoDoc, and update the example.

Also fix JSON writer edge cases:
- avoid panic on empty message lists
- preserve newline semantics when the last message already ends with n
- keep original message argument types for custom writers when no replacers are configured

Update dependencies and add release notes for the next release.

Raw Blame History

v1.2.0

Highlights

Added message replacement with Logger.AddReplacer(old, new) for masking secrets or normalizing log output.
Preserved the existing LoggerWriter.Print(...any) contract, so custom writers do not need a signature update.
Improved JSON writer newline handling for messages that already end with \n.

Added

Logger.AddReplacer(old, new) appends a replacement rule that is applied before records are sent to writers.
README and package GoDoc now document message replacement and include usage examples.
Tests covering message type preservation for custom writers, JSON empty messages, and JSON trailing newline behavior.

Fixed

LoggerJsonWriter.Print no longer panics when called with no message arguments.
LoggerJsonWriter.Print now treats a trailing newline at the end of the last message as newline semantics and does not include that newline in the JSON message field.
Log messages keep their original argument types for custom writers when no replacement rules are configured.

Changed

Updated the example program to demonstrate AddReplacer.
Updated dependencies:
- github.com/fatih/color from v1.18.0 to v1.19.0
- github.com/mattn/go-isatty from v0.0.20 to v0.0.21
- golang.org/x/sys from v0.42.0 to v0.43.0

Compatibility

No breaking API changes are intended in this release. The public LoggerWriter interface continues to accept messages ...any.
