Document restored direct-model compaction, request-lifetime tool access, clearer cancellation and sidebar controls, reduced redundant startup work, and slimmer package inputs. Keep published Agent 0.15.0 and prior release notes unchanged. Review both feature matrices and retain Office editing as planned work. Typecheck, lint and bilingual notes validation passed; 85 focused tests passed and one POSIX-only test was skipped on Windows. Full source validation and production build remain CI gates before tagging.
