Add ChatCrystal skills 🤖🤖🤖

[ZengLiangYi]

Adds three ChatCrystal Agent Skills:

• chatcrystal-task-recall
• chatcrystal-debug-recall
• chatcrystal-task-writeback

ChatCrystal provides local-first memory recall and writeback for AI coding sessions through ChatCrystal Core and MCP. Each skill includes degraded-mode behavior when ChatCrystal Core or MCP access is unavailable.

Validation run locally:

• npm install
• npm run skill:validate
• npm start

The public source repo also exposes these skills via npx skills add ZengLiangYi/ChatCrystal --list.
