feat(core): implement centralized structured json log manager module …

[Hrithik-ui753]

📝 Description

This PR addresses Phase 1 of the Structured Logging feature request (#232). It introduces a central logging utility architecture that formats log records into structured, predictable JSON objects instead of plain-text strings, setting up foundation blocks for system observability.

🚀 Feature Reference

Closes part of #232 (PR 1/3)

🛠️ Changes Made

• Created core/utils/logger.py containing a robust JSONFormatter.
• Implemented get_structured_logger(module_name) to support module-isolated log identification.
• Added support for extra structural keyword fields (action, status) to match the proposed specification payload format.
• Suppressed root logger propagation to eliminate text-formatting collisions with default console streams.

📊 Standardized Output Verification

Calling the tracker emits the following schema structure flawlessly:
