摘要 / Summary

准备 dsh-mnemon v0.3.4：更新 package 版本与全部当前发布入口，并新增同步的中英文发布说明，汇总已合并的全局用户档案与项目记忆组合、Git 分支范围热记忆、可配置 Runtime 容量预算、多目标归档兜底，以及 rewind 后引导提示恢复。

Prepare dsh-mnemon v0.3.4 by updating the package version and every current-release entry point, and by adding synchronized English and Chinese release notes for the already-merged global-profile overlay, git branch-scoped hot memory, configurable Runtime capacity budgets, multi-target archive fallback, and guided-reminder recovery after rewind.

仓库规范检查 / Repository Rules

• 未修改 DSH 官方源码，未让 tsconfig 指向 DSH 源码 checkout，仅使用正式的 @deepseek-ai/* NPM 契约。 / I did not modify DSH source or point tsconfig at a DSH source checkout, and used only published @deepseek-ai/* NPM contracts.
• Client 与 Host 边界仍以 src/shared/contracts.ts 为准，没有在两侧重复定义 wire DTO。 / The Client and Host boundary still uses src/shared/contracts.ts as the single source for wire DTOs.
• 持久化格式、RPC 权限、路径或凭据处理的变更包含兼容或拒绝路径、安全分析和相应测试。 / Changes to persistence formats, RPC authority, paths, or credentials include compatibility or rejection paths, security analysis, and tests.
• 没有提交 token、密钥、私有记忆、未脱敏日志或生成的 lib/ 文件。 / I did not commit tokens, credentials, private memory, unredacted logs, or generated lib/ files.
• 用户可见文案和长期文档已同步维护中文与英文版本，命令、配置键和路径保持一致。 / User-visible copy and long-lived documentation are synchronized in Chinese and English, with matching commands, configuration keys, and paths.
• 新增和修改的代码、注释、文档、提交信息不含 emoji。 / New and modified code, comments, documentation, and commits contain no emoji.

兼容性与数据安全 / Compatibility and Data Safety

本 PR 相对已合并的 main 只修改 package 版本与发布文档，不再改变运行时代码、配置、RPC、Provider 或持久化格式。v0.3.4 无需数据迁移：现有配置保持 v0.3.3 行为；启用全局用户档案叠加不会复制、合并或删除任一根的数据；工作区 Pack 刻意排除独立全局档案；回滚到 0.3.3 无需反向迁移，但旧版本会暂时把带 branches 字段的条目投影到所有分支。

This PR changes only release metadata and documentation relative to merged main. It adds no runtime, configuration, RPC, Provider, or persistence changes. v0.3.4 requires no migration: existing configuration preserves v0.3.3 behavior; the global-profile overlay never copies, merges, or deletes either root; workspace Packs intentionally exclude the separate global profile; and rollback to 0.3.3 needs no reverse migration, although older versions temporarily project records carrying branches on every branch.

本地验证 / Local Validation

执行的命令 / Commands run:

pnpm install --frozen-lockfile
pnpm run verify
npm pack --ignore-scripts --json
pnpm exec dsh --version
git diff --check origin/main...HEAD

结果摘要 / Result summary:

• pnpm run verify passed on exact commit 161981a: typecheck; 48 test files passed with 522 passed tests and 1 expected Windows-only skip; two deterministic builds covering 106 files; Headless activation with 35 total tools and 5 representative Mnemon tools; package contents with 113 files, 378,158 packed bytes, and 1,713,376 unpacked bytes; 10 public Node entry imports; strict publint and are-the-types-wrong.
• The inspected dsh-mnemon-0.3.4.tgz reports version 0.3.4, contains exactly 113 entries, and has SHA-256 40e17d684a5de80a03fed16d91f5575942f7a347b3b4a7e6f64d5d02d7a087f2.
• The exact dependency lock installed successfully under Node v25.1.0 and pnpm 11.19.0; the published DSH dependency reports v0.1.1-rc.2.
• git diff --check passed, no generated lib/ files are tracked, and the worktree is clean after the release commit.
• The existing missing sourcemap warning from @deepseek-ai/dsh-client-ui-primitives remained non-failing.
• CI retains Linux coverage on Node 22.19 and 24, Windows coverage on Node 24, the official Mnemon Windows CLI smoke, and the Node 20 public-entry compatibility smoke.

用户可见变更证据 / Local Feature Evidence

证据 / Evidence:

N/A. This PR changes release metadata and synchronized documentation only. The isolated Web evidence for the already-merged capacity controls and global-profile scope selection is retained in PRs #102 and #103; the other shipped paths are covered by the targeted regression tests referenced in their merged PRs.
