📋 Task Description

Add support for JSON output format when running queries, enabling integration with other tools and scripts.

🎯 Acceptance Criteria

• Add --output-format option with values: table (default), json
• When json is selected, output query results as valid JSON
• JSON should be well-structured and parseable
• Works with the export command as well

🔗 Related Files/Components

• File: codebase_rag/cli.py - add output format option
• File: codebase_rag/main.py - modify result display logic

📝 Additional Context

This enables:

• Piping results to jq for processing

• Programmatic access to query results

Example usage:

graph-code query "find all functions" --output-format json | jq '.functions[].name'

Example JSON output:

{
  "query": "find all functions",
  "results": [
    {"name": "process_file", "module": "parser.py", "line": 42},
    {"name": "validate_input", "module": "utils.py", "line": 15}

@vitali87 the query functionality seems to be missing. Do you have any updated examples that I could use?
