What's Changed

• Fix navigation readiness detection: per-target lifecycle event storage, and handle same-document navigations without burning the readiness timeout.
• Fix markdown extraction destroying URLs and dropping long link lines.
• Detect LLM output truncation instead of failing with misleading parse errors, and let truncation errors switch to the fallback LLM.
• Keep plain BrowserErrors recoverable and preserve structured error memory through execute_action.
• Fix visibility check mutating shared snapshot bounds.
• Pin Browser Harness to 0.1.5 (Windows reliability, more robust telemetry, cloud-browser suggestion).
• CLI polish: shim for legacy CLI commands, hints for unknown commands, faster startup, better error tracking.
• Restructure README quickstart around the CLI and Python library paths.
