Summary

Combines two overlapping fork PRs that both rework src/adapters/cursor/envelope-echo.ts:

• Retain adjacent mid-stream echo diagnostics: echo evidence adjacent to the mid-stream envelope is preserved instead of dropped.
• Bound output-guard reasoning quarantine: reasoning quarantine in the output guard is bounded rather than unbounded.

Tests

• bun test tests/providers/cursor/cursor-envelope-echo-retry.test.ts — 47 pass
• cursor-adapter.test.ts + cursor-tool-continuation.test.ts — 54 pass

Summary by CodeRabbit

• Bug Fixes

  • Improved handling of unusually large or closely spaced streamed responses.
  • Limited temporary retention of streamed output while preserving detection of relevant response markers.
  • Improved independent detection of multiple response integrity issues.
  • Ensured oversized responses are released and delivered normally when they exceed the safe processing limit.

• Documentation

  • Documented bounded handling for streamed response output and oversized frames.
