Simplify code-search skill description for clarity

Streamline description to focus on core use case (codebase navigation)
rather than exhaustive feature list. Update table to include call flows
as explicit use case.

-description: Systematic code understanding and search using AST-based structural patterns (ast-grep) and fast text search (ripgrep). Use when exploring unfamiliar codebases, finding function/class usages before refactoring, locating security issues (hardcoded credentials, SQL injection, eval usage), analyzing imports/dependencies, or finding specific code constructs (error handling, API calls). Triggers on questions like "where is X used", "find all calls to", "show me functions that", "how is this pattern implemented", and security audits.
+description: Use when exploring codebase, architecture, or call flows.

 # Code Search
 
-AST-based structural search reveals hidden relationships, security vulnerabilities, and architectural issues that text-based grep misses. Combine with fast text search for comprehensive codebase understanding.
+Use when navigating code, tracing how functions/classes connect, finding where symbols are defined or called, or answering "how does this work" questions about a codebase.
