Breaking Changes

• Agent run lifecycle rework - stop() is now async and resolves only after the run fully settles. Run status is decoupled from task outcome: a new stopped state was added, and LLM self-reported failures now end as completed. Lifecycle hooks re-throw instead of folding errors into the result, agent errors are recorded in history, and agent.lastResult was added.

Features

• Abortable JavaScript execution - execute_javascript now honors the AbortSignal.
• Leaner agent prompts - Simplified the waiting-response flow and removed navigation-back instructions to reduce LLM cognitive load.
• MultiPageAgent safety - Disabled ScriptExecutionTool for MultiPageAgent.

Improvements

• Dark mode detection - Refined detection heuristics and made isMainContentDark less aggressive by checking html and body data attributes independently.
• Extension lifecycle robustness - Drove heartbeat and running state from status changes, cleared stale activity on any non-running status, handled the stopped lifecycle state, and cleared currentTabId on TabsController.init.

Bug Fixes

• Accurate wait reporting - Wait steps now report the actual wait duration.
• Scroll predicates - Scroll predicates now return booleans.
• Docs - Fixed the broken demo video on GitHub.
