MagAgent 0.32.9

MagAgent 0.32.9 focuses on daily-driver UX polish. It adds direct goal execution via magent goal --run, stronger goal-loop guidance for verification and artifact completion, improved missing-content recovery for generated files, interactive /retry, /undo, /usage, and /insights commands, safer trusted shell-pattern management for read-only pipelines, tool backend readiness commands, local skill browsing, and a conservative magent update helper. Docs and tests were updated; unit suite passes with 293 tests.
