LoopX v0.4.3

LoopX v0.4.3

LoopX v0.4.3 continues the effect-interpreter control-plane evolution: a
second real EffectTurn interpreter for turn results, data-encoded execution
mode, an ordered effect program shape, a replacement-first runtime plan, and a
unified bilingual Dev Book with an independent Control-Plane Course chapter.

Release Decision

Who should upgrade: Maintainers and users who follow the stable
install/update path should move to v0.4.3. Users who only consume the CLI or
Dev Book can remain on v0.4.2, but the new control-plane contracts and course
material are the recommended baseline.

What this release solves: The release makes LoopX's effect-interpreter
story concrete in code, not only docs: turn results and quota packets share
one canonical EffectTurn lens, execution strategy becomes data, and the Dev
Book exposes the Control-Plane Course as an independent learning path.

Breaking changes: No. No persisted state migration is required.

How to verify:

loopx --version
loopx doctor
loopx canary premerge --from-git-diff

Install / Update

New users should install from the named stable ref. Existing users should
preview the update, then execute it explicitly:

loopx update --check --ref stable
loopx update --execute --ref stable
loopx doctor

中文摘要

升级决策

谁需要升级： 维护者、安装 stable 通道的用户，以及希望跟随最新
Control-Plane Course 与 effect-interpreter 合约的开发者。

解决了什么： 把 effect interpreter 从文档推进到可复用代码透镜，增加
turn-result 解释器、execution mode 与有序 effect program 形状，并把 Dev Book
的 Control-Plane Course 独立成章。

是否有破坏性变更： 无。

如何验证：

loopx --version
loopx doctor
loopx canary premerge --from-git-diff
