enhancement: add --json flag to search command #90
Description
Found during dogfooding v2.3.0
Severity: Low (feature gap)
Command: codegraph search
Description
All query commands (query, fn, fn-impact, context, explain, where, map, stats, hotspots, structure, diff-impact) support -j/--json for machine-readable output, but search does not.
Running codegraph search "query" -j returns error: unknown option '-j'.
Expected behavior
search --json should output JSON with an array of results including name, kind, file, line, and similarity score.
Use case
Piping search results to other tools or scripts for automated workflows.
