Module logger 

Logging module for codesearch

Provides centralized logging configuration with:

• Daily log file rotation (via tracing-appender)
• Periodic cleanup of old log files (by age and count)
• Per-database log storage in .codesearch.db/logs/
• Configurable via environment variables

Daily rotation creates files named codesearch.log.YYYY-MM-DD. Cleanup removes files older than retention_days and enforces max_files.
