v0.7.79

Every actual review-level change now automatically syncs the configured review repo, including TUI grades, lc review level, and autograde verdicts. Same-level/clamped operations do not start needless network work; sync failures report themselves without undoing the safely recorded local grade.

Built-in-editor submits no longer emit a false bookkeeping warning after the verdict was already recorded; an old duplicate result-display call referred to judge-local data outside its scope.
