Support COBOL Ecosystem Code Indexing

Problem to Solve

COBOL remains a critical language in enterprise systems, particularly in financial services, insurance, government, and healthcare sectors. Billions of lines of COBOL code power mission-critical applications worldwide. Many organizations are modernizing legacy COBOL systems and need better code intelligence tools. Currently, the Knowledge Graph lacks COBOL support, limiting code intelligence features for COBOL developers and enterprise teams.

Proposed Solution

Implement a COBOL parser that extracts code entities (programs, divisions, sections, paragraphs, variables) and their relationships (calls, data dependencies, file operations) so the Knowledge Graph can index and search COBOL codebases intelligently.
