Adds core/compact modules (micro, threshold, summarize, reactive, tracking) with tests to reclaim context tokens and summarize conversations. Extend agents types and StreamChunk with RequestPlanApproval, HookProgress/HookResult, RequestHookTrust, AllowedPrompt, PlanApprovalResponse and HookTrustResponse/HookTrustEntry. Wire UI/streaming changes in the CLI to render plan-approval and hook-trust dialogs and handle user input, and expose plan-approval handling in the desktop Tauri frontend. Reorganize several tools modules (lsp, mcp) and add many SDK tooling files (bash, file_ops, navigation, plan, subagent) and related type updates; bump Cargo package versions in Cargo.lock to 0.1.13.
