  The `search_symbol` MCP tool handler searches for symbols in the workspace using the `TyLspClient`.

  @mcp.tool()
  async def search_symbol(query: str) -> str:
      """Search symbols (classes, functions, variables) across the project."""
      client = _get_client()
  
      try:
          symbols = await client.search_workspace_symbols(query)
  
          if not symbols:
              return _not_found(f"No symbols matching '{query}'")
  
          results = []
          for sym in symbols:
              uri = sym.get("location", {}).get("uri", "")
              path = _uri_to_path(uri)
              name = sym.get("name", "?")
              kind = SYMBOL_KINDS.get(sym.get("kind", 0), "Symbol")
              range_info = sym.get("location", {}).get("range", {}).get("start", {})
              line = range_info.get("line", 0) + 1
              col = range_info.get("character", 0) + 1
              container = sym.get("containerName", "")
              results.append({
