claude-code sessions, chat logs and agents

Key features

• Import sessions from pi (JSONL), opencode (SQLite), codex (JSONL), and claude-code (JSONL) — as real, resumable dsh sessions.
• dsh-import-agents imports sessions, chat history, and agents from pi, opencode, codex, and claude-code into DeepSeek Harness (dsh).
• Each user message opens a turn (turn/start + user/message)
• verify.mts — mounts the real dsh JSONL backend + skill provider on staged output (node --import tsx/esm ../dsh-import-agents/verify.mts from the dsh checkout) → expects SESSIONS ALL PASS / SKILLS ALL PASS.
• Browse the full original history (text, reasoning, tool calls) and continue the conversation — the model gets the complete context.
