Summary

Query result row limits (RFC 0017) with early-stop scanning, truncation metadata, MCP byte guard, and schema include_system fixes.

中文摘要

• 默认上限：CLI/Web 1000 行，MCP 500 行；MCP max_rows: 0 = 未设置（走默认链），负值拒绝。
• MCP mcp.max_rows_limit（默认 10000） clamp 超大请求，metadata 含 max_rows_requested / max_rows_limit。
• 截断字段：truncated_reason（max_rows / max_response_bytes）、max_rows 为配置上限、max_response_bytes、合并 hint。
• MCP 字节裁剪改为二分查找；CSV 截断时 stderr 提示，stdout 纯 CSV，退出码 0。
• 已合并 main（含 ci: Codecov hardening and release smoke tests #83）；截断 hint 与 internal/errors/hints.go 一致。

Testing

go build / go vet / go test ./... / integration (MySQL 8.0, PG 16) / e2e / golangci-lint
