Paperclip agent instructions via instructionsFilePath in adapter_config.

Paperclip agent instructions via instructionsFilePath in adapter_config. Instructions injected via adapter_config.instructionsFilePath → Paperclip reads file → writes combined version to skillsDir → passes to claude —append-system-prompt-file. Path must be container-internal (e.g., /home/node/.claude/agent-instructions/architect.md). Host path /root/.claude/agent-instructions/ maps via existing volume mount. Rule: Store files at /root/.claude/agent-instructions/ on host, reference as /home/node/.claude/agent-instructions/name.md in DB.
