MemoStem plugin v0.6.2

What's changed

• Renamed the public skill to memostem, covering getting started, explicit saves, consent-based suggestions, retrieval, draft review status, and recovery.
• Added the ChatGPT App plugin package and language-aware getting-started guidance.
• Expanded guest-shelf capture, link recovery, account transfer, and structured concept guidance.
• Refreshed ChatGPT submission prompts and review cases, and added a 62-second recording of guest save, shelf viewing, and preview without saving.
• Aligned package, marketplace, and MCP Registry metadata at version 0.6.2.

This release distributes the public plugin and remote-server metadata. ChatGPT directory review and approval are separate and are not completed by this release.
