fr.json covers the messages main added since #1224 (render workspace, design properties, display quality, surface untrim, joint drive stops, Save as Mesh), with the same terminology conventions.
The Joint and As-built Joint dialogs explain why picks make no joint and offer Create Components from Bodies when every pick is on one component; joint.create and joint.as_built suggest component.from_bodies. Labels in all catalogs. Fixes#1239.
Fixes#1187. New parameters.move {name, before|after} reorders user parameters (the design's own params order, so it is saved with no format change, and undoable); the Parameters dialog's user rows get up/down buttons. Label in every catalog. I merged main in. Checked on main + this branch: cargo check --workspace, the engine parameters tests, the UI parameter_order test, and docs/features.md regenerates unchanged.
Part of #771 and #772. solid.sweep and surface.sweep take orientation (perpendicular, parallel or a direction), twist (up to 4 turns) and end scale (0.01 to 100), applied about the profile's normal through the path's start; default options run the old sweep, so existing sweeps are unchanged. New fields are optional, left out when unset and noted under format 21; twist and scale are model parameters. Both sweep dialogs get Orientation, Twist and End Scale rows; labels in every catalog. Checked on main + this branch: cargo check --workspace, kernel/engine/UI sweep tests, the doc suite and the robustness goldens.
joint.drive answers moved, and a reason (with unconnected) when the joint can move nothing; motion.play answers moved and unmoved; joint.list answers floating chains. joint.drive values come back in joint.list's shape (deg/mm). quiet: true trims joint answers and motion.play poses. A single value keeps a joint's other values. Drive Joints shows the floating case (drive.unconnected, all locales).
Adds a French catalog as a partial locale (missing strings fall back to English, like Russian), registered in the language list, with tests and attribution.
