v0.1.52

Fixed

• Serialize Cursor provider turns per pi session scope so parallel same-session Cursor model evaluations cannot supersede each other's SDK session agent or drain the wrong live run. Queued aborts now return an aborted stream without creating a Cursor SDK agent or leaking the turn queue.

Validation

• npm run check:platform-smoke, npm run typecheck, npm test (796 tests), and npm publish --dry-run pass locally.
• npm run smoke:platform:all passes on macOS, Ubuntu, and Windows native with Cursor auth. Artifact index: .artifacts/platform-smoke/latest.json.
• Subagent review/fix loop and thermo-nuclear release review completed with final NO FINDINGS.
