Full Release Notes

### Breaking Changes

- **Lifecycle: `stop()` vs `dispose()`** - New `stop()` method to cancel the current task while keeping the agent reusable. `dispose()` is now terminal — a disposed agent cannot be reused. This affects both `PageAgentCore` and `PanelAgentAdapter`.

### Features

- **Panel action button** - The panel button now morphs between Stop (■) and Close (X) based on agent status
- **Error history** - Errors and max-step failures are now recorded in `history` as `AgentErrorEvent`, making post-task analysis more complete

### Bug Fixes

- **AbortError handling** - `AbortError` is no longer retried by the LLM client, and shows a clean "Task stopped" message instead of a raw error stack
