AI coding agent with plans, history, and safer apply flows

OL Code now includes a fuller AI coding agent experience with a standalone assistant panel, plan approval, debug mode, usage visibility, conversation history, and file history. The agent can work with packed host workspaces, search for related members, use compile templates, run permitted test flows, and apply approved edits while protecting local changes. See [[feature:ai-coding-agent|AI coding agent]] for the standing capability.
