### 新增
- 分享查看器：消息上添加“复制链接”按钮，用于分享可直接导航到特定消息的 URL（[#477](https://github.com/badlogic/pi-mono/pull/477) by [@lockmeister](https://github.com/lockmeister)）
- 扩展示例：添加 `claude-rules` 以将 `.claude/rules/` 中的条目加载到系统提示词中（[#461](https://github.com/badlogic/pi-mono/pull/461) by [@vaayne](https://github.com/vaayne)）
- 无头 OAuth 登录：所有提供商现在均显示粘贴输入框，支持手动输入 URL/代码，可在无 DISPLAY 环境的 SSH 下运行（[#428](https://github.com/badlogic/pi-mono/pull/428) by [@ben-vargas](https://github.com/ben-vargas), [#468](https://github.com/badlogic/pi-mono/pull/468) by [@crcatala](https://github.com/crcatala)）
### 更改
- OAuth 登录 UI 现使用专用的对话框组件，边框样式保持一致
- 除 `dumb`、空终端或 `linux` 外，假设所有终端均支持真彩色（修复 SSH 下的颜色显示问题）
- OpenAI Codex 清理：移除按思考级别划分的模型变体，思考级别现单独设置，且提供商会根据各模型内部支持情况进行限制（初始实现在 [#472](https://github.com/badlogic/pi-mono/pull/472) by [@ben-vargas](https://github.com/ben-vargas)）
### 修复
- 压缩期间提交的消息会被排队，并在压缩完成后交付，以保留引导和后续交互行为。扩展命令在压缩期间会立即执行。（[#476](https://github.com/badlogic/pi-mono/pull/476) by [@tmustier](https://github.com/tmustier)）
- 托管二进制文件（`fd`, `rg`）现存储于 `~/.pi/agent/bin/` 而非 `tools/`，消除了误报的弃用警告（[#470](https://github.com/badlogic/pi-mono/pull/470) by [@mcinteerj](https://github.com/mcinteerj)）
- 在 `settings.json` 中定义的扩展未能加载（[#463](https://github.com/badlogic/pi-mono/pull/463) by [@melihmucuk](https://github.com/melihmucuk)）
- 修复了运行多个 pi 实例时 OAuth 刷新导致用户登出的问题（[#466](https://github.com/badlogic/pi-mono/pull/466) by [@Cursivez](https://github.com/Cursivez)）
- 迁移警告现忽略 Windows 下 `tools/` 目录中的 `fd.exe` 和 `rg.exe`（[#458](https://github.com/badlogic/pi-mono/pull/458) by [@carlosgtrz](https://github.com/carlosgtrz)）
- CI：将 `examples/extensions/with-deps` 添加至工作区以修复类型检查（[#467](https://github.com/badlogic/pi-mono/pull/467) by [@aliou](https://github.com/aliou)）
- SDK：传入 `extensions: []` 现按文档说明禁用扩展发现功能（[#465](https://github.com/badlogic/pi-mono/pull/465) by [@aliou](https://github.com/aliou)）
### Added
- Share viewer: copy-link button on messages to share URLs that navigate directly to a specific message ([#477](https://github.com/badlogic/pi-mono/pull/477) by [@lockmeister](https://github.com/lockmeister))
- Extension example: add `claude-rules` to load `.claude/rules/` entries into the system prompt ([#461](https://github.com/badlogic/pi-mono/pull/461) by [@vaayne](https://github.com/vaayne))
- Headless OAuth login: all providers now show paste input for manual URL/code entry, works over SSH without DISPLAY ([#428](https://github.com/badlogic/pi-mono/pull/428) by [@ben-vargas](https://github.com/ben-vargas), [#468](https://github.com/badlogic/pi-mono/pull/468) by [@crcatala](https://github.com/crcatala))
### Changed
- OAuth login UI now uses dedicated dialog component with consistent borders
- Assume truecolor support for all terminals except `dumb`, empty, or `linux` (fixes colors over SSH)
- OpenAI Codex clean-up: removed per-thinking-level model variants, thinking level is now set separately and the provider clamps to what each model supports internally (initial implementation in [#472](https://github.com/badlogic/pi-mono/pull/472) by [@ben-vargas](https://github.com/ben-vargas))
### Fixed
- Messages submitted during compaction are queued and delivered after compaction completes, preserving steering and follow-up behavior. Extension commands execute immediately during compaction. ([#476](https://github.com/badlogic/pi-mono/pull/476) by [@tmustier](https://github.com/tmustier))
- Managed binaries (`fd`, `rg`) now stored in `~/.pi/agent/bin/` instead of `tools/`, eliminating false deprecation warnings ([#470](https://github.com/badlogic/pi-mono/pull/470) by [@mcinteerj](https://github.com/mcinteerj))
- Extensions defined in `settings.json` were not loaded ([#463](https://github.com/badlogic/pi-mono/pull/463) by [@melihmucuk](https://github.com/melihmucuk))
- OAuth refresh no longer logs users out when multiple pi instances are running ([#466](https://github.com/badlogic/pi-mono/pull/466) by [@Cursivez](https://github.com/Cursivez))
- Migration warnings now ignore `fd.exe` and `rg.exe` in `tools/` on Windows ([#458](https://github.com/badlogic/pi-mono/pull/458) by [@carlosgtrz](https://github.com/carlosgtrz))
- CI: add `examples/extensions/with-deps` to workspaces to fix typecheck ([#467](https://github.com/badlogic/pi-mono/pull/467) by [@aliou](https://github.com/aliou))
- SDK: passing `extensions: []` now disables extension discovery as documented ([#465](https://github.com/badlogic/pi-mono/pull/465) by [@aliou](https://github.com/aliou))
