Add a new /copy slash command that extracts chat content through OSC 52 clipboard (with temp-file fallback for oversized text). - /copy (no args) → copies the latest assistant response - /copy all → copies the serialized chat conversation - /copy N → copies the last N serializable items New src/cli/ui/copy-history.ts handles card-to-text serialization covering all card kinds (user, assistant, tool, reasoning, diff, plan, task, usage, memory, subagent, search, etc.). /copy is restricted to local TUI sessions only — remote QQ/ Telegram/Weixin slash commands cannot trigger host clipboard writes. Fixes esengine#2260 (copy portion)
