Type: type on a path, glyphs follow the curve (#4365) (#4377)

* Type: type on a path, glyphs follow the curve (#4365)

Add TextShape::Path (path, start offset, flip). The text is laid out as one
point-text line and each glyph is placed rigidly on the flattened path by arc
length, turned to the tangent at its centre; glyphs past the end are hidden and
a degenerate path falls back to straight text. New commands type.attachToPath
(work path or shape layer subpath) and type.detachFromPath. TextShape is no
longer Copy. .pcraft round-trips the new variant.

* Automation policy: type.attachToPath/detachFromPath take document vector paths, not host files (#4365)
