### Zig 0.16 Compatibility
### Zig 0.16 and 0.17 Development Compatibility

Starting from Zig 0.16, the standard library underwent significant changes to the I/O subsystem. The `std.io.FixedBufferStream` was removed as part of a broader redesign. This library includes a compatibility layer (`src/compat.zig`) that:

- Provides a `BufferStream` implementation for Zig 0.16+ that mimics the behavior of the old `FixedBufferStream`
- Uses conditional compilation to maintain backward compatibility with Zig 0.14 and 0.15
- Ensures all existing functionality works seamlessly across different Zig versions
- Keeps the same buffer-stream API on Zig 0.16 and 0.17 development builds
- Is exercised by CI on Zig `0.16.0` and the latest `master` development build

This means you can use the same API regardless of your Zig version, and the library will handle the differences internally.
The current minimum supported Zig version is `0.16.0`; older compatibility branches in the source do not imply support for older compilers. Code formatting is checked with Zig `0.16.0`, since development compiler formatters may introduce syntax migrations.

Update all stale Zig support guidance in AGENT.md and CLAUDE.md. These tracked instruction files still claim Zig 0.14/0.15 support and reference the removed CI matrix. They also contain stale compatibility checks and examples. Align them with the Zig 0.16.0 minimum, master development support, and current CI workflows. No other checked-in support or CI configuration requires this update.

### Zig 0.16 兼容性
### Zig 0.16 和 0.17 开发版兼容性

从 Zig 0.16 开始，标准库的 I/O 子系统经历了重大变更。作为更广泛重新设计的一部分，`std.io.FixedBufferStream` 被移除。本库包含一个兼容层（`src/compat.zig`），它：

- 为 Zig 0.16+ 提供了一个 `BufferStream` 实现，模拟旧版 `FixedBufferStream` 的行为
- 使用条件编译来保持与 Zig 0.14 和 0.15 的向后兼容性
- 确保所有现有功能在不同 Zig 版本间无缝工作
- 在 Zig 0.16 和 0.17 开发版上保持相同的缓冲流 API
- 通过 CI 在 Zig `0.16.0` 和最新的 `master` 开发版上进行验证

这意味着无论您使用哪个 Zig 版本，都可以使用相同的 API，库会在内部处理差异。
当前最低支持 Zig `0.16.0`；源码中保留的旧版兼容分支不代表仍支持旧编译器。代码格式检查固定使用 Zig `0.16.0`，因为开发版编译器的格式工具可能引入语法迁移。
