✨ 新功能 / Features

  • SSOT Core 层响应式内核 — 基于长期开发经验打造的零外部依赖 push-based 响应式系统。完整迁移路线：

    • 基础设施：signal / computed / effect / batch 响应式原语（packages/core/src/foundation/reactivity/signal.ts），零外部依赖，支持批量原子更新与自动依赖追踪
    • 核心设计原则：单一可信源（每段状态有且仅有一个 writable signal）、自动推导（派生值存放于 computed()，禁止手写 syncXxx()）、读写分离（外部消费 ReadonlySignal，内部通过 Action 方法操作 WritableSignal，TypeScript 编译时强制边界）、Effect 隔离（DOM/WebGL 副作用仅在 effect() 中执行）、批量原子更新（batch() 合并多次变更成一次通知周期）
    • 子状态模块：完成 settings、mode、pane、drawing、theme、indicators、data、zoom、viewport、interaction、comparison、subPane、marker、renderer、options 共 15 个模块的 SSOT 化，消除所有手工同步路径与 passthrough 层
    • 参考实现：packages/core/src/engine/state/viewportState.ts、packages/core/src/engine/state/stateKernel.ts

    SSOT Core Reactive Kernel — A zero-dependency push-based reactive system built from long-term development experience. Full migration scope:

    • Primitives: signal / computed / effect / batch (packages/core/src/foundation/reactivity/signal.ts), zero external deps, batched atomic updates, automatic dependency tracking
    • Design Principles: Single Source of Truth (exactly one writable signal per state fragment), Automatic Derivation (derived values in computed(), no hand-written syncXxx()), Read/Write Separation (external ReadonlySignal, internal mutations through Actions on WritableSignal, TypeScript-enforced boundary at compile time), Effect Isolation (DOM/WebGL side effects in effect() only), Batched Atomic Updates (batch() coalesces multiple writes into one notification cycle)
    • Modules Migrated: All 15 sub-state modules — settings, mode, pane, drawing, theme, indicators, data, zoom, viewport, interaction, comparison, subPane, marker, renderer, options — converted to SSOT pattern; all manual sync paths and passthrough layers eliminated
    • Reference: packages/core/src/engine/state/viewportState.ts, packages/core/src/engine/state/stateKernel.ts
