Job-Specific File Logging

Description

A dedicated logging system for jobs will be implemented. When enabled, each job writes its detailed operational logs, including progress and debug messages, to a unique log file.

Implementation Notes

• The logging logic will be implemented in src/infrastructure/jobs/logger.rs.
• Configuration is managed via JobLoggingConfig in src/config/app_config.rs.
• The JobExecutor creates a FileJobLogger instance for each job it runs, passing it down through the JobContext.
• Log files are stored in the job_logs directory within the library path.

Acceptance Criteria

• When enabled in the config, running a job creates a corresponding .log file.
• Progress, info, and error messages from the job context are written to the file.
• The logger respects the include_debug configuration flag.
