Tool-execution error/telemetry logs now redact tool names and truncate error content by structure, not raw text

Local debug log lines for tool input validation errors, validate-input rejections, permission denials, and runtime tool errors no longer include a raw slice of the offending input, message, or error text. Instead they report structured details: issue codes, byte/character counts, and error codes. These log lines also now use a new classifier that labels skill tools, MCP tools, and dynamically-named tools with a generic label like skill_tool, mcp_tool, or dynamic_tool instead of printing the tool's literal name.
