[Draft] Added structured JSON logback logger encoder

[GoodforGod]

• Adds new logging-logback-json module with JSON Logback encoding support.

Main pieces:

• JsonReadyLogbackRecordEncoder JSON shell for Logback events
• JsonBootstrapLogbackRecordEncoder for early bootstrap JSON logs
• LoggingEventJsonWriter extension point for custom event fields
• default writers for event fields, trace/span, structured data, and exceptions
• LogbackJsonModule / lifecycle wiring for DI-based writer collection
• JSON masking support via JsonLoggingEventMasker
• structured data, args, mdc, exception stacktrace output
• Supports two-phase startup: bootstrap encoder first, DI-configured encoder after graph init.
