Plugin & Skill Manager v0.4.6

v0.4.6 — Consistent source and delivery packages

Unifies the public source, complete installation ZIP, standalone desktop ZIP and private account plugin at version 0.4.6. Includes the service icons previously delivered in the private 0.4.4 update and the bilingual product-purpose copy from 0.4.5.

Both plugin manifests, the MCP server, embedded dashboard and distribution integrity metadata derive their version from package.json. The build now includes the Chinese package README, generates the compatibility manifest and places review cases in the MCP configuration. Release notes come from this versioned file; future packages no longer need manual metadata overlays.

The English and Chinese source READMEs retain the prominent product purpose and concise installation links. Removed release-news paragraphs stay removed. Existing historical releases and release notes remain unchanged.

No ledger format, counting rules or cleanup permissions change. Missing records do not prove non-use. Upgrade through the same installation channel already in use; avoid a second registration. The complete ZIP includes an installer and local catalog; the desktop ZIP has plugin.json at its root. The source ZIP is for development. SHA256SUMS identifies the exact downloadable archives.

Validation results are recorded in docs/VALIDATION.md. Protocol, package and installation checks do not establish native desktop visual acceptance or official directory approval.

中文：统一公开源码、完整安装包、桌面根目录包和私有插件的版本及构建来源。补齐服务图标、双语说明和兼容配置，保留 README 前部的产品用途，旧版本历史不改写。升级沿用原安装渠道，不重复注册；数据格式、统计口径和清理权限不变。
