cli: add memory_history, remove dump-json/edges/lookups

- Add memory_history MCP tool for version history
- Convert cmd_history to use memory_rpc
- Add raw parameter to memory_render for editing
- Remove unused: dump-json, list-edges, lookup-bump, lookups
- Fix render_node path in defs.rs/subconscious.rs

+// Bridges OpenCode events to the consciousness system:
+//   - chat.message → forwards to poc-hook-opencode, appends output as text part
+//   - tool.execute.after → signals response activity
+//   - event → tracks session lifecycle (idle, compacted, etc.)
+//   - shell.env → injects POC_SESSION_ID into subprocesses
+//
+// Install: copy this directory to your project's `plugin/` or `plugins/` dir,
+// or add to opencode.json:
+//   "plugin": ["/home/kent/poc/consciousness-claude/opencode-plugin"]
