v0.3.0

Breaking adaptation to DSH core 0.1.2-rc.1 (peer/engine raised to dsh >=0.1.2-rc.1):

• settings: section is now registered via ctx.settings.register(ns, Config, { base }), live value read from scope.get() (the standalone installSettingsSection / settingsNamespace exports were removed in dsh-settings 0.1.2).
• session: events are read through session.snapshotEvents() (Session.events was removed in dsh-session 0.1.2).
• docs: README badges and AGENTS.md updated to the new API.

DSH 核心 0.1.2-rc.1 破坏性适配(最低核心要求抬到 >=0.1.2-rc.1):

• 设置:改用 ctx.settings.register + scope.get()(dsh-settings 0.1.2 移除 installSettingsSection / settingsNamespace)。
• 会话:事件改用 session.snapshotEvents()(dsh-session 0.1.2 移除 Session.events)。
• 文档:README 徽章与 AGENTS.md 已同步新 API。
