MCP instructions field in initialize response

Claude Code (and any MCP-compatible client) now receives usage instructions automatically on server connect — no CLAUDE.md entry or SessionStart hook required.

The instructions tell the model to:

• Call retrieve_memory on every session start with the current project/task as the query
• Store preferences, credentials, architectural decisions, and gotchas proactively
• Query Recall whenever the user references context that might be in memory

This makes Recall self-activating from first connection rather than requiring explicit prompting from the user.
