[Feature] Support structured JSON logs (Logback JSON format)

[AbaSheger]

Many Spring Boot apps log in JSON format (via logstash-logback-encoder). StackLens currently only handles plain text logs.

Example JSON log line:

{"timestamp":"2024-01-15T10:30:00","level":"ERROR","message":"java.lang.NullPointerException","stack_trace":"..."}

Would require detecting JSON log format and extracting the relevant fields before running detectors.

Hi @AbaSheger,

I'm interested in implementing support for structured JSON logs (Logback format). Since StackLens currently only handles plain text, adding a parser for logstash-logback-encoder will significantly improve log analysis.

My proposed approach:

1. Implement a Detection Logic to identify JSON formatted lines.
2. Use Jackson to extract key fields like level, message, and stack_trace.
3. Ensure compatibility with the existing detectors.

I have experience with Logback configurations and Spring Boot, and I'd love to contribute this feature. May I be assigned to this?
